What's new

2026-08-27

15.5.0

You can now choose how a product is marked with the reaction it came from. Settings → Product suffix. Second and third table:

• Letters — MDX-113B, MDX-113C (what it has always done)
• Letters after a dash — MDX-113-B, MDX-113-C
• Numbers — MDX-113-2, MDX-113-3

Tick Mark the first table too and the first reaction stops being bare: MDX-113A, MDX-113-A or MDX-113-1 instead of MDX-113.

• It applies to both routes — the Register link in a stoichiometry row and the panel button that writes the ID onto a batch you registered earlier.
• Parallel reactions keep their pair letters — MDX-113-1A — so the ID still matches the letter beside the row.
• Letters with a bare first table stay the default. Nothing changes until you switch it.

2026-08-25

15.4.3

You can now edit a saved phrase. Settings → Phrases, then ✎ on the row. Fix a typo, change a volume — links to CDD records inside the phrase stay links, so type around them. Save keeps it, Cancel drops it.

This extension is not a CDD product, and the settings page now says so. If CDD misbehaves, switch the extension off, reload the page and check whether it still happens — report it to CDD support only if it does. Otherwise open an issue.

Copying text out of a stoichiometry table is switched off in this version. It was losing work: if you added a link with @ and then edited the table without reloading the page in between, the link — and anything else you had typed since opening the entry — disappeared.

• Dragging to select table text, Ctrl/Cmd+click to copy one field and Ctrl+C for a whole grid are unavailable for now.
• Nothing else changes, and no setting needs touching.
• Until it is back, use CDD's own Export, or the panel's Export button for the reaction rows.

If you have seen an ELN entry lose text after editing a reaction table, this was it. Entries already saved are unaffected.

2026-08-24

15.4.2

Synonyms are now offered in the row Name editor by default. Click *Name: Optional* in a stoichiometry row and the molecule's other names are listed under the box — DIPEA rather than N-ethyldiisopropylamine. Typing your own still works, and what you type is offered first the next time.

• Nothing is written for you. Filling a name automatically is still a separate choice under *Settings → Row name from synonym*.
• If you switched the feature off yourself, it stays off.
• Hover a plate name in search results and you see its location again — the Ctrl+click hint no longer covers the bubble.
• The toolbar above the results no longer offers a Ctrl+click copy it never performed, and the row-select switch ticks the row again instead of copying an empty column.
• The setup guide opens by itself only the first time you open the settings page. The ⚙ in the panel goes straight to the settings; the guide is behind Setup guide at the top of that page.

2026-08-23

15.4.0

Ctrl+click a value in a search results table and it goes to the clipboard. Same gesture you already use on a column header, now on a single cell — an IP address, a batch name, a molecule id — no selecting the text by hand.

• The cell flashes green and a message confirms what was copied.
• Ctrl+click on a link in the table now copies it instead of opening it in a new tab. Click it normally to open it.
• The row's checkbox still works as a checkbox.

2026-08-23

15.3.0

A setup guide walks you through the extension. Nine short steps: what shows up where in CDD, and the switches worth deciding up front — your vault's identifier format, what the floating panel shows, table filling, the entry ID on registered batches, HPLC, the registration form.

• It opens on its own the first time you open the settings page.
• Open it again any time: Setup guide at the top of the settings page, or the new ⚙ in the floating panel's header.
• Every switch in the guide is the same switch as in settings — change it in either place.

One Export button in the panel. *Export* prints the table (save as PDF from the print dialog); its ▾ holds *CSV* and *CSV — products only*.

The panel's print sheet now has a proper header — entry title, Experiment ID, source and print time — and the same footer as the stoichiometry sheet.

2026-08-23

15.2.0

Products of a parallel reaction now get their own ELN ID. Instead of one table letter for the whole block, each product is suffixed -1A, -1B, …: the number is which parallel reaction of the entry it is, the letter is the pair's letter in the table. A second parallel reaction gives -2A, -2B, …. Applies to the Register link and to the panel's *Write … into Internal ID* button alike; ordinary reactions keep their old suffix.

The floating panel lost its Refresh button and its CDD title. The button never reloaded anything — the panel already redraws itself whenever the entry, the table or a setting changes. The header (*Entities | Phrases*, *Print*, *CSV*) now sits on one row.

2026-08-23

15.1.0

A stoichiometry row can name itself. A row's free-text *Name* is filled from the names the molecule already answers to, so a table reads DIPEA instead of N-ethyldiisopropylamine.

• Switch it on at *Settings → Remembered batch values → Row name from synonym*. Suggest in the Name editor lists the candidates under CDD's own Name box when you click Name: Optional; Suggest, and fill automatically also writes the name into rows you add while working. Rows that were already in the entry when you opened it are never written to on their own.
• The name is chosen in one order: a name you typed for that molecule before, then its shortest synonym, then the batch's Internal ID for a substance whose registrant gave no synonym.
• Adding a reagent names the row straight away — the synonyms come from the search you just did, so nothing waits for the entry to save. A substance the search returns no synonyms for gets no automatic name; pick one from the list in the Name editor instead.
• Names you type yourself are remembered per molecule and offered wherever that molecule turns up, including in other entries. See *Settings → Remembered names*. A name that is simply the shortest synonym is not stored — the memory is for the choices that differ from it.
• Off by default: each new molecule costs one request for its page.

Save a phrase once, paste it anywhere. Select text in an ELN entry and click *Save phrase*; the phrase keeps its formatting.

• The panel's Phrases tab groups them by category, and one click copies.
• File, rename, delete, export and import at *Settings → Phrases*. Up to 50 phrases; past that, the one copied longest ago is dropped.

The ELN entry steps aside for the panel. While the panel is open the entry sits at the left edge of the window instead of the middle, so on a laptop the panel lands in the empty margin rather than over the table's right-hand columns.

• On by default. To keep CDD's centred layout, untick *Settings → Panel fields → move the ELN entry to the left edge*.
• On a narrow screen (1366 px, or 150 % display scaling) the panel may still overlap a little — drag its left edge to make it narrower.

The ELN entries filter has the same field picker as Inventory. Open the filter and click the field dropdown: the built-in ELN fields and your vault's own fields sit side by side, with a search box that has the cursor as soon as the panel opens. Type to narrow the list, Enter or a click picks, Escape closes.

Also fixed

• The panel showed 0 sample(s) on an entry until the entry was next saved.
• A card's *Fill name* button stayed on screen after the name had been written, until the next save.

2026-08-21

14.12.0

The HPLC injection block now shows just the number. Click its header to open the calculator when you need to change the aliquot, the vial or the target.

• It speaks up only when the injection is genuinely too big or too small. When it does, the volume is struck through and the one you should be aiming for appears next to it, with a line underneath saying what to do — *Use a 250 µL insert, take 3 drops*. Click that line to set it.
• The comfortable range now starts at 0.1 µL and runs to 5, so an ordinary small injection no longer asks you to re-dilute. If you set your own range it is kept — *Settings → HPLC injection → Comfortable injection range* has a reset button.
• A reaction using its own aliquot or vial is marked with an amber dot next to the title.

2026-08-21

14.11.0

A compound that was registered before it was made can now be pointed back at the entry it came from. On a product card, Write … into Internal ID saves this entry's ID onto that batch.

• It shows only while the batch's Internal ID is empty, and never on a reactant. If the field already has a value, the card shows that value instead.
• This one saves to the batch record, not to the stoichiometry table — closing the tab does not undo it. It takes a few seconds and names each step as it goes.
• Switch it on in *Settings → Panel fields*.
• Product cards now also show the batch's own fields, the same ones reactant cards show.

2026-08-21

The sample cards say the same things in less space.

• No more "Reaction 1" on every card. The group heading and the card's coloured edge already told you. The reaction is now a large, faint R1 in the bottom-right corner of the card, in that reaction's colour — it takes no room at all.
• The note about remembered values is an ⓘ on the fill button it belongs to. Hover it for the full sentence; it used to take two lines on every card that had one.

2026-08-21

Registering a compound from an ELN entry now fills itself in, and the HPLC block tells you what to change.

• Origin, and anything else you always type. Set it once in *Settings → Registration defaults*, per vault. Filled only when you register from an ELN entry.
• Initial amount and units come from the stoichiometry row as soon as you tick *Create a New Sample*.
• The injection block tells you the fix when the volume is outside your comfortable range: more drops, a different vessel, or dilute the aliquot. Click the sentence to apply it to that reaction only.
• Injection volumes round to 0.1 µL, matching the printed UPLC guide.
• Your injector range and comfortable range are settings. The ceiling is your sample loop's, so change it when the loop changes.
• Entry ID only as a tab title — *Settings → ELN Tab title*.
• Settings is now a list and one pane instead of eight cards at once.

Fixes: the sample amount never filled at all; the injection block showed an empty amber strip; the panel could reopen off-screen after you moved it on a bigger monitor, or be made too narrow to collapse; the low-purity badge was the hardest text in the panel to read; scrolling the page could silently rewrite a number you had clicked.

2026-08-20

The panel can work out your HPLC injection volume.

Every number for it is already on the page — the stoichiometry table prints the reaction molarity on the solvent row — but the sum was still being done by hand each time. Now a block at the top of each reaction group does it: you draw an aliquot from the mixture, dilute it into an HPLC vial, and the block tells you how much of that to inject to land your target amount on the column.

• It gives you the number you can actually dial in. Injections go in half microlitres, so that is what the block leads with. The exact figure stays underneath, next to what the rounded injection really delivers — exact 0.30 µL · 0.333 nmol on column. Rounding 0.30 up to 0.50 is two thirds more compound, and you should be able to see that rather than find out later.

• Each reaction has its own numbers. One assay takes a single drop, the next takes two. Type a different aliquot into one block and only that reaction changes — the settings and every other reaction stay where they were. The field is marked while it differs, and a reset chip puts it back.

• Several solvents are handled properly. The block combines them into the concentration of the mixture your aliquot actually comes from, rather than picking one row and hoping.

• It warns instead of quietly lying. An injection that would exceed the vial volume turns red. One that had to be pushed up to the 0.5 µL minimum says so, because it means the vial is too concentrated and you are overshooting.

Switch it on in Settings → HPLC injection. It is off by default — it answers a question only some workflows ask, and your panel should not sprout a new box because you updated. The card also holds the starting values every block begins from: aliquot 10 µL, vial 1.5 mL, target 0.2 nmol.

2026-08-19

14.8.0

*Everything since 14.5.0, the last version that reached the stores. The 14.6.0 and 14.7.0 numbers were used while this work was being written and tested, and were never published on their own — what they added is here.*

The panel can tell you what a compound is also called.

• **Tick *Synonym* under Panel fields and every card gets its synonym.** Reagents, products and the batches you linked in the entry text — all of them. If a compound has several synonyms you get the first one, which is the one CDD shows at the top of the molecule page.
• It is off until you switch it on, and that is deliberate. The synonym is not part of what CDD sends the panel; it has to be looked up on each compound's own page. While the box is clear the plugin never makes those lookups, so nobody pays for a row they do not want. Tick it and the panel you already have open fills in — you do not have to reopen the entry.
• The synonym travels with everything else: it becomes a column in the print sheets and in the CSV export, exactly like any other panel field.

Molecule-Batch ID joins the panel fields too.

• **Tick *Molecule-Batch ID*** and every card shows the identifier CDD prints for the batch, e.g. RGT-0001620-001. It was missing from the list until now — no reason beyond it never having been added.
• **It is not the same as *Batch name*.** That row shows what the entry sends for the batch on its own, usually just the 001 on the end; the new row is the whole identifier, molecule name included. Cards that come from links in the entry text already carry the full ID, and it is shown as it is.
• Batches CDD calls *Unspecified* have no identifier, so those cards simply have no row. Both halves are already in what the panel receives — ticking this one looks nothing up.

The CDD Samples panel resizes.

• Grab an edge and pull. Either side, the bottom, or a bottom corner. Pull the left edge and the panel grows to the left — the right-hand side stays where it is instead of the whole panel sliding across.
• You can see where to grab. There is a small grip mark in the bottom-right corner, and any edge you can pull lights up as your cursor reaches it.
• The size is remembered, along with the position. Come back tomorrow and the panel is the shape you left it. If you move to a smaller screen it is trimmed to fit rather than hanging off the edge.
• Collapsing the panel still shrinks it to its title bar; your size comes back when you expand it again.

Panel fields is easier to read.

• The fields you have switched on sit at the top, in the order the panel shows them. Everything you have not picked follows underneath in alphabetical order, so finding one no longer means reading the whole list. The same goes for your vault's own fields further down.
• The list settles when you open the settings page. Ticking a box does not make the others jump around under your cursor — the new order shows up next time you open it.

Two smaller fixes.

• **"Create N Samples" no longer sits in the debit dialog while *Create sample from debit* is unticked.** With that box clear, saving records the debit and creates no sample, so the button was offering something that could not happen. It appears the moment you tick the box, with the wells you picked still selected.
• Forgetting the last saved run-definition template no longer prints its "nothing saved yet" note twice.

Under the hood. A pass over the whole code base with a static analyser: clearer control flow in a handful of places, no behaviour meant to change, and the build's own toolchain updated away from three published vulnerabilities.

2026-08-18

14.5.0

*Everything since 14.1.0, the last version that reached the stores. The 14.2.0, 14.3.0 and 14.4.0 numbers were used while this work was being written and never published on their own — what they added is here.*

You can finally copy out of a stoichiometry table.

• Drag across the table and it goes blue, like any other text on the web. Until now nothing in it could be highlighted — not a compound name, not a mass, not a formula weight — because CDD switches text selection off for the whole reaction block and turns any attempt to drag into a drag of the block itself. Both are now out of the way.
• Ctrl+C fills the clipboard for real. Being able to highlight the table turned out to be only half the job: CDD's editor takes the copy over for itself, and because it does not consider the reaction table to be text it had nothing to hand across — you could select the whole reaction and still paste an empty cell. The plugin now gets there first.
• Highlight several cells and you get a table. Paste into Excel and the rows and columns land where you would expect them — one spreadsheet row per table row, one column per column. Everything in a cell keeps its label, so FW: 231.05 g/mol | Density: 1.23 g/cm3 stays readable instead of turning into two loose numbers. Highlight inside a single cell — a compound name, a mass — and you get exactly what you highlighted, nothing added around it.
• Ctrl+click (⌘+click on a Mac) a value and it is on your clipboard. One click, no popup opens, the field flashes green. This is the quick way to lift a compound name out of a row. Add Shift to get the label too — Ctrl+click gives 231.05 g/mol, Ctrl+Shift+click gives FW: 231.05 g/mol.
• Inside the table Ctrl+click always means *copy*, batch links included: Ctrl+clicking PHA-0333427-001 copies the id instead of opening it in a new tab. An ordinary click on the link still opens it as before.
• A field that only shows Optional or Required copies nothing — you get no clipboard full of the word "Required".
• Everything you did before still works. A normal click still opens the edit popup for that value; only a drag that actually highlighted something stops the popup from appearing on release, so a selection you just made doesn't get covered up. Copying anywhere else in the entry is untouched.

Register a product from a reaction and the entry ID is already in the form.

• **Click *Entity: Register* in a stoichiometry row and the new tab opens with the ELN entry's ID already typed into Internal ID.** CDD already carried the structure and the project across; the one thing that says *where this compound came from* is now carried too, so it no longer has to be copied out of the other tab.
• The vault prefix is left behind. On CDD's *Vault-User Identifier* format an entry ID reads PHA-MDX-0095, and the PHA- in front is the same on every entry in the vault — it says nothing you do not already know from where the batch lives. What gets registered is MDX-0095.
• If the entry has more than one reaction, the table you registered from is in the ID too. The first stoichiometry table registers as MDX-0095, the second as MDX-0095B, the third as MDX-0095C — so months later it is still clear which reaction in the entry a batch came out of. An entry with a single reaction gets no letter on the end.
• Only an empty field is filled. If something is already in Internal ID, it stays. If you clear the field yourself, it stays cleared. If you are typing in it at that moment, nothing is touched.
• Switching the project or the registration form does not lose it. CDD rebuilds the whole form when either changes, which throws away anything already in it — the ID is put back.
• It only happens when you started from an ELN entry. Register links elsewhere in CDD behave exactly as before.
• Settings → Registration form → From the ELN. Switch the whole thing off there, or change which field receives the ID if your vault calls it something else — the star does not matter, Internal ID and *Internal ID are the same field, and so are different capitalisation and spacing.
• Settings → … → ELN identifier format. The same three choices CDD lists under its own ELN settings — *Global Identifier*, *Vault Identifier*, *Vault-User Identifier*. Only the last has a vault prefix to drop; the other two are carried whole. New installs start on Vault-User. It is set here rather than read from CDD because that page needs admin rights to open — and an ID that does not actually read vault-user-number is left whole whatever the setting says, so a differently shaped ID can never come out cut in half.

2026-08-18

Editing a number in a stoichiometry table stops fighting you.

• Click an amount and the number is already selected — type the new one and you are done. No more deleting 19 g character by character just to make it 25 g. The unit stays sitting after the cursor, so it survives the retype on its own. This applies to every number in the row: Mass, Volume, Purity, Density, Equivalent, Concentration.
• A cleared field can no longer change the unit without telling you. Mass and Volume keep their unit inside the box, but the popup's own label says Mass [mg] — so wiping the field and typing 25 used to save 25 mg, a thousandfold off, looking exactly like a normal edit. Now the unit that was there comes back when you press Enter.
• If you *want* a different unit, nothing is in your way: type 25 mg and that is what gets saved. Clear a field on purpose and it stays cleared. Click into the middle of the value and the cursor stays where you put it.

The Samples panel's CSV button now opens.

• CSV still downloads the whole table in one click. The small arrow next to it adds Products only — just the reaction products, for when the sheet you need is the one about what came out.
• That export gives you the products whether or not the panel is currently showing them, since asking for them is answer enough. If the entry has no product rows, it tells you instead of handing you an empty file. It saves as cdd-products-…, so it will not overwrite your ordinary export.

Bulk reactions no longer invent a product.

• A parallel (bulk) reaction remembers the scheme it was drawn from, and CDD shows the varying slots as *Variable reagent* and *Variable product*. The panel used to read the leftover structure behind that product slot and give it a card — a compound that appears in no table on the page, which then followed you into Print and CSV. It is gone. The real enumerated products are all still there.

2026-08-18

14.0.0

*Everything since 13.1.1, the last version that reached the stores. The 13.2.0, 13.3.0 and 13.4.0 numbers were used while this work was being written and never published on their own — what they added is here.*

The Samples panel now sees what you link in an entry's text.

• A batch or sample linked anywhere in an ELN entry's body gets its own card, in a *Mentioned in text* group under the reactions, with the same fields as any other card. Links into another vault work, and so do links that came with an embedded card rather than typed in.
• A sample card shows that bottle — where it is, how much is left. A batch card deliberately shows no location or amount: the entry mentioned the batch, not one particular bottle. A bottle since used up still gets its card, with the usual DEPLETED badge.
• Nothing appears twice. A substance already in a stoichiometry table is not repeated as a mention, and the status line says how many were hidden.
• Print and CSV include the mentions. In the settings you choose what the panel draws from — table rows, links in the text, or both; an entry with no reaction table now gets a panel too, if it links to something.

Stop retyping the same run definition.

• Run Details → Run Definition has a new bar: save the values under a name, then fill them into the next run. You tick what belongs to the method when you save — *Run Date* and *Person* start unticked, because they belong to that one run.
• Filling writes the empty fields and leaves everything else alone. A field already holding something different is shown as what's there → what the template has, and you take the template's value for that one field, or for all at once.
• The plugin never presses Save. It loads the form and stops, so you read it before anything reaches CDD — Cancel still throws it away. *Fill* and *Paste* wait until you have opened Edit run definition yourself.
• Copy and Paste into form cover the one-off case through the clipboard, so the values also paste into Excel. On a protocol's Run Data tab, every run row has a copy link of its own.

Stock solutions fill themselves — solvent included.

• The plugin already remembered a density, purity or concentration you typed for a batch whose record had none. It now remembers the solvent of a stock solution the same way and offers them together: one click clicks Make solution, writes the concentration and picks the solvent.
• The solvent doesn't have to be on CDD's list. One of the 38 built-ins is picked from the list, so it brings its CAS-RN, FW, density and boiling point along; anything else — *EtOAc/Hexane 1:1*, a buffer, a mixture — is written as plain text. Neither way adds anything to the vault's solvent list.

Both field pickers can be narrowed to one registration form.

• The Search page's Keywords selector and Inventory's Filter Entries selector list every field the vault owns — 129 in the vault this was built against. A row of chips above the columns (All, Molecule, Plasmid, Antibody, …) cuts that to the fields the chosen form actually uses: 21–46 options.
• Default is All, and the choice is remembered per vault. CDD's own built-in columns stay visible whichever form you pick, and the chips work alongside the search box rather than against it.

Fixed.

• The Samples panel could sit on *Waiting for reaction data…* and never show its cards, on any entry that had something to show.
• The panel stayed on screen after you navigated away from an ELN entry, still listing that entry's samples. It now goes when you leave and comes back when you return.

2026-08-12

Ctrl+click a section heading to copy the whole block of columns.

• New: the search results table groups its columns under headings like Properties and Batch Fields. Ctrl+click one of those and you get the entire block at once — all 30 property columns, or all 5 batch columns — laid out as columns when pasted into Excel, with the column names on the first line. Ctrl+click on a single column header works exactly as before, and pastes as a plain list without a heading.
• Fixed: Ctrl+click on the toolbar above the table (*Export*, *Add to collection*, *Save this search*…) did nothing in 13.1.0, because the toolbar sits inside the table header and the copy feature captured the click. Those buttons work again.

2026-08-12

Copy a whole column from search results with one click.

• New: on a search results table, hold Ctrl (Cmd on a Mac) and click a column header — *Batch Name*, *Molecule-Batch ID*, *Internal ID*, whatever — and the entire column is copied to the clipboard, one value per line. Paste straight into Excel. The cells flash green and a short message tells you how many rows were copied.
• Columns line up: where a molecule spans several batch rows, its value is repeated for each row, so you can copy two columns one after the other and paste them next to each other without anything shifting.
• The *Molecule* column copies just the identifier (TEST-0260386), not the project name shown beside it.
• A normal click on the header still sorts as usual — only Ctrl+click copies.

2026-08-12

The heat map well popup got wider.

• Changed: the balloon that opens when you click a well on a run heat map is now 1.4× wider. Since you can add your own batch fields to it, its rows kept wrapping onto two lines — even short ones like *Batch name: 001*. The text column roughly doubles (136 → 223 px on a real popup), so most rows now fit on one line. Very tall content is still capped by CDD's own limit, and a popup opened near the right edge of the window is nudged left so it stays fully visible.

2026-08-12

Mark control layouts by dragging a rectangle — and save them for reuse.

• New: editing a control layout (Run Details → Control Layouts → Edit this layout) no longer means clicking every well and cycling it through the states until it lands on the right one. Pick Positive control, Negative control, Reference molecule or Clear in the new *Paint wells* bar, then drag a rectangle over the plate — every well inside it changes as you drag. Pull the rectangle back and the wells you passed over return exactly to what they were.
• New: click a row or column header to fill that whole line, the empty corner header to fill the entire plate, or shift+click to stretch a rectangle from the last well you marked.
• New: Saved layouts. Give the current plate a name, and load it back on any run later — separate lists for 96-, 384- and 1536-well plates, so a 96-well layout can never land on a 384-well plate. Loading fills the grid; CDD's own Save changes button is still what stores it in the vault.
• Works on the 96/384/1536-well run defaults and on plate-specific layouts.
• Click the highlighted colour button again to switch the whole thing off — CDD's normal one-well-per-click behaviour comes straight back.

2026-08-12

The samples panel stays where you put it.

• Reverted: 12.8.7 made the panel jump back inside the window whenever the window was resized. In practice that meant the panel kept moving on its own, away from the spot you had chosen for it. That is gone — you drag the panel by its header exactly as before, and it stays there.
• Unchanged: the panel still remembers both its position and whether you left it collapsed, so it comes back the way you left it.
• Note: as before 12.8.7, a position chosen on a large screen can put the panel out of reach if you later work in a much smaller window. If that happens, clear cdd-stoich-panel-state in the browser's local storage for the CDD site, and the panel returns to its default top-right corner.

2026-08-12

The CDD Samples panel can no longer hide outside the window.

• Fixed: if you dragged the panel somewhere on a large screen and later worked in a smaller window, the panel was restored at its old position — off the right edge, out of reach. It looked as if the plugin had stopped working, even though the panel was there with all its samples loaded. It is now pulled back into view whenever it would fall outside the window, including when you resize the window, and the corrected position is remembered. If the panel is taller than the window, its header row stays visible so you can always grab and move it.

2026-08-12

Printed sheets no longer hide the solvent a reagent is dissolved in.

• Fixed: when a reagent is used as a solution — say *N-methyl(3-bromo-2-nitrophenyl)amine* as a stock in benzene — the PDF printed it as if you were weighing out the neat compound. The solvent is now printed as its own indented Solvent line right under the reagent, with CAS-RN, FW, density, boiling point, mass, volume and mole, just like CDD shows it on screen. Solutions where the solvent has not been chosen yet print as *Solvent: not specified*, keeping the volume you typed.
• New: solution rows now also print their Concentration, and solvent rows their Reaction molarity — both in mol/L, matching the table on screen.

2026-08-09

Plate map export splits every sample code, not just some.

• Fixed: in Export Plate Map (CSV), wells whose sample code mixes letters and digits — like I88-SM-0060050-005-I88S034537 — dumped the whole name into the Batch ID column and left Sample ID blank. Both columns are now filled correctly. Wells that carry only a batch id (PHA-0334442-001) still show it whole, with Sample ID empty.

2026-08-07

Heat map tooltip starts blank — you choose.

• No more preset rows: the well popup shows nothing extra until you pick the fields yourself in the settings. Hover a heat map once, the "Available" list fills with your vault's batch fields, tick and order what you want. Removing everything switches the extra rows off again.

2026-08-07

The tooltip defaults are back.

• Fixed: the heat-map tooltip settings could come up with nothing selected (and the popup showed no extra rows) if an older version had stored an empty list. Synonyms + Internal ID now always apply as the default — and if you ever remove every row, they simply come back.

2026-08-07

You decide the tooltip order.

• The heat-map tooltip rows now come in the order you arrange in the settings — move them with the ▲/▼ arrows, remove with ✕. Everything, synonym included, shows in one block right under the molecule link; no more fields scattered in vault order with the synonym stranded at the bottom.

2026-08-07

Heat map tooltip: tick, don't type.

• The "Heat map tooltip" settings card now fills itself: hover any run heat map once and your vault's batch fields appear as checkboxes, in the same order as your batch form. Tick what you want — no more typing field names.
• Batch fields like Internal ID now show at the top of the popup, right under the molecule link. The synonym (first one only) stays at the bottom, so a long chemical name doesn't shove the structure image around.

2026-08-07

Heat map tooltips that tell you what's in the well.

• Hover a well on a run's heat map and CDD's popup now also shows the molecule's synonym and the batch's Internal ID — right under the concentration readouts, loaded in the background as you move the mouse.
• You pick the rows. A new "Heat map tooltip" card in the settings takes one batch field name per line, in the order you want them — Purity [%], Vendor ID, whatever your vault defines. Case and the * required-marker don't matter (Internal ID finds *Internal ID). Clear the list to switch the extra rows off.

2026-08-07

Export a plate map to CSV.

• Every plate page now has an Export Plate Map (CSV) link right in the Plate Details / Projects / Plate Map tab bar. The file lists every occupied well — barcode, well position (A01…P24), the full entity name, and that name already split into Batch ID and Sample ID columns — ready for Excel or a picking robot. Plates without a barcode field use the plate name as the barcode.

2026-08-07

Even more no-sample quotes.

• The NO SAMPLE cards now rotate through 74 quotes — cold cases, wildlife documentaries, corporate memos and other reminders that a bottle without a sample is just a rumor with a cap.

2026-08-07

More no-sample quotes.

• The NO SAMPLE cards in the Samples panel now draw from 35 quotes instead of 18 — fresh reminders (and gentle teasing) about why that bottle deserves a sample record. Still one quote per card per day.

2026-08-07

Products, thresholds you control, and a CSV button.

• Products in the panel (optional). Tick the new checkbox in Panel fields and every reaction's products appear as PRODUCT-badged cards with the same fields as your reagents — and in the print sheets too (a Products section per reaction, a Type column in the panel print). Products are display-only: nothing gets written to them.
• You decide what counts as low purity. Two settings, both starting at 93 %: one decides when a purity fill is offered at all, the other when the ⚠ LOW PURITY badge appears.
• CSV export. The panel's new CSV button downloads exactly what Print shows, ready for Excel.
• Fixed: filling purity now reliably puts your Equivalent back — the old check could silently give up when Chrome throttled a background tab, leaving the recalculated value behind. Keep the tab in front for long runs; Fill all now says so.

2026-08-07

Purity and concentration join the remembered values — and can fill themselves.

• The batch memory now covers density, purity and concentration. Type a value once and every later appearance of that batch offers it back with one click. Registration data still rules: a purity/density on the batch record or a concentration on the sample always wins and retires the remembered copy. The purity fill even puts your Equivalent back the way it was after CDD's recalculation, and the concentration fill clicks "Make solution" for you when needed.
• One click to fill everything. The panel's new ⤵ Fill all missing values (N) button runs every offered fill in sequence — keep the tab visible while it works.
• Experimental auto-fill (off by default). Tick the checkbox in settings and rows you ADD while working fill themselves; entries you merely open are never touched automatically.
• Settings page: the remembered-values card grew per-field columns and double width.
• Reliability: fills now target rows by their printed table number, so the right row gets the value even when the same batch appears twice in one reaction; assorted redraw-loop and stale-offer fixes.

2026-08-07

The extension now remembers densities you type — per batch, everywhere.

• Type a density once, get it offered forever. When you fill a density into a stoichiometry row whose registered batch has none, the extension quietly remembers it (up to 100, per molecule batch). Next time that batch shows up without a density — any entry, any reaction — its card offers ⤵ Fill remembered density into table, with a gentle amber reminder that the proper home for the value is the batch record itself. A density saved on the batch always wins and retires the remembered copy.
• See and manage what's remembered. The settings page gained a Remembered densities card: every stored value with its batch name, density and date, a ✕ to forget one, and Clear all for a fresh start.

2026-08-06

One click puts the batch's density into the stoichiometry table.

• Batch-only cards can now fill the table's Density field for you. When a reagent has no sample but its registered batch knows the density, the card shows a ⤵ Fill density into table button. One click and the extension does exactly what you would: opens the row for editing, clicks the Density field, types the value and confirms — CDD recalculates the volume and saves as usual. If anything on the page doesn't look the way it should, nothing is written and the button tells you to fill it manually instead.

2026-08-06

Batch-only cards get a sense of humour (and a mission).

• The BATCH ONLY tag grew into an amber ⚠ NO SAMPLE badge with a random educational quote. Every card that shows registered-batch data instead of a real inventory sample now ends with one of eighteen rotating one-liners reminding you that creating a sample is the proper way — ranging from the sober *"This purity is from registration day, not from the bottle on your shelf."* to *"Schrödinger's reagent: both full and empty until someone makes a sample."* Collect them all — or just make a sample.

2026-08-06

Reordered reactions no longer print with the wrong table.

• Fixed: after moving reactions around inside an ELN entry, the printed stoichiometry sheet could show the right reaction scheme with a different reaction's reagent table — and the CDD samples panel grouped samples under the wrong reaction number. The extension used to read reactions in the order they were created, while the page shows them in the order they appear in the entry; once you dragged a reaction to a new spot, the two got out of sync. The extension now follows the entry's actual layout, so the table, scheme and samples panel always belong to the reaction you clicked.

2026-08-06

Purity and density without a sample — batch-only rows join the panel.

• The CDD Samples panel no longer ignores reagents that don't have an inventory sample. If a stoichiometry row references a registered batch (say RGT-0001620-001) rather than a specific sample, the panel now shows a card for it anyway: it quietly looks the batch up on its molecule page and pulls in the registered metadata — purity, density, vendor ID, internal ID and any other batch fields your vault records. There's no reason you shouldn't see a reagent's purity just because nobody made a sample of it.
• Batch-only cards are labelled. A grey BATCH ONLY tag tells you the card's data comes from the registered batch, which is also why sample-side details like Location or Concentration aren't there.

2026-08-06

Bulk-reaction print sheets now use letters, matching CDD.

• Printed stoichiometry sheets label bulk-reaction rows A, B, C… instead of numbers. In a parallel (bulk) reaction, CDD lists each variable reagent and its product together under a letter — but the printed report used to number those rows 1–17 like any other. Now the PDF mirrors the page: the fixed rows keep their normal 1, 2, 3… numbering, and below them a "Reagents and products" section shows each pair as its own framed block — the letter in a shaded band on the left, with the variable reagent and its product stacked inside and clearly tagged. Reports for ordinary single reactions look exactly as before.

2026-08-06

Goodbye, filter auto-switcher — CDD does it natively now.

• Removed the "smart filter default" helper. It used to flip a freshly added ELN/Inventory filter from "Any value" to the second operator for you. CDD now ships this behaviour itself, so the extension no longer needs to watch the page and simulate clicks — same result, less background work in your browser.

2026-07-15

Bug fix: the Keywords picker on the Search page scrolls smoothly to the end in Firefox.

• Finishing the 12.1.2 fix. In Firefox, the long columns of the field picker could still stop short of their last options, and the Search page's Keywords picker had it worst: while scrolling inside it, the list jittered near the top and kept snapping back, so the bottom entries were effectively unreachable. The picker no longer mistakes scrolling inside its own list for page scrolling, remembers your scroll position while it re-measures itself, and gives its columns an exact height so Firefox lets you reach the very last option. Chrome behaves exactly as before.

2026-07-14

Bug fix: in Firefox, the field picker's columns can now scroll all the way down.

• No more unreachable options at the bottom. In Firefox, the long Entity and Batch columns of the wide field picker (Inventory filter and the Search page's Keywords selector) cut off their last options — the scrollbar ran out before the list did. The columns now measure their height correctly in every browser, the last option is fully visible and clickable, and the list keeps a little breathing room at the bottom. Chrome behaves exactly as before.

2026-07-14

Bug fix: the plugin's tweaks now survive navigating within CDD.

• No more "it only works after a refresh". If you moved to the Inventory page (or a registration form) by clicking through CDD instead of reloading it, several of the plugin's touches — the filter operator default, the wide filter field picker, the Column Manager, form defaults and more — quietly stopped applying until you refreshed the page. That's fixed: CDD replaces the page content in place when you navigate, and the plugin now watches the page in a way that survives that replacement. Everything applies immediately, however you arrive.

2026-07-14

The Search page's "Keywords" field picker gets the same treatment as the Inventory filter.

• Choosing what to search is no longer one endless dropdown. On the Search page, the Keywords field selector used to be a single long, narrow list mixing the general choices, every Entity field and every Batch field together. Now it opens as the same wide, multi-column picker you already know from the Inventory filter — General, Entity and Batch side by side, each with its own heading and scroll, and a search box at the top that ranks matches (an exact name wins over a loose one), ignores case and accents, hides everything irrelevant, and highlights the part you typed. Just start typing the field name — you don't even need to click first.
• Nothing you could pick before is gone. Every original choice is still there, including "Entity Fields" and "Batch Fields" themselves (which search across a whole object) — they now sit in the General column, and picking any field does exactly what it did in the old dropdown. Your saved searches and results are unaffected.
• The picker stays attached to the field you clicked. It drops right below the Keywords selector, and when there isn't room it repositions sensibly while staying connected to that field — so it's always clear which selector it belongs to.

2026-07-12

Finding and choosing attributes stops being a scroll-fest.

• The Inventory filter's attribute picker is now four columns, not one endless list. When you add a filter and open the field selector, instead of one long narrow dropdown mixing everything together you get Sample, Batch, Entity and Event side by side, each with its own heading and scroll. There's a search box at the top that ranks matches (an exact "Sample ID" wins over a loose match), ignores case and accents, hides everything irrelevant, and highlights the part of the name you typed. Picking a field behaves exactly as before.
• "Select and reorder columns" became a proper Column Manager. On a vault with a hundred-plus columns the old flat list was painful. Now there's a header showing how many columns are visible out of the total, a search that even copes with fuzzy typing, and Sample/Batch/Entity/Event chips (with counts) to jump to one type. Each field carries a small coloured category badge instead of an italic "(Sample)"; the columns you've selected are tinted and are the only ones showing a drag handle — so it's obvious at a glance what's on and what isn't. Selecting and drag-reordering work exactly as before.
• The bulk-registration type list now remembers, like the Create Entity page does. When you register many entities at once, the entity-type picklist arrives in your configured order and preselects whichever type you last used in that vault. It shares that memory with the Create Entity page, so both agree on what you last worked with.
• Got feedback? There's now a link. Report a bug or ask for something at https://github.com/xaviersvk/CDD-Stoich-Tools/issues — linked from the manual and from the top of this page.

2026-07-10

Find out what changed, without leaving the extension.

• The settings page now tells you which version you're running, and links straight to this page. It's in the top-right corner, next to the version number.
• This page itself is new: every release, in plain language, at https://xaviersvk.github.io/CDD-Stoich-Tools/. Each version also gets its own entry on GitHub, so you can link a colleague to exactly the change you mean.
• The plugin's flask now heads both the settings page and this one, and sits in the browser tab as the favicon. The blue you see in the buttons and highlights is taken from that icon, so the whole thing finally looks like one piece of software rather than three.

2026-07-10

A real settings page, and a Create Entity page that remembers how you work.

• Settings moved out of the little popup. Clicking the extension icon now opens a proper settings page with four columns side by side: tab title, panel fields, prefix colours, and the new registration-form settings. You can also reach it from CDD Plugin options, which now sits in CDD's own user menu next to Account.
• Put the registration forms in the order you actually use them. The Registration Form picklist on the Create Entity page arrives in CDD's order, which suits nobody. Drag the forms into your own order on the settings page and the picklist follows. Someone working on cells puts Eukaryote on top; someone doing chemistry puts Molecule there.
• The Create Entity page can preselect a form for you. By default it picks whichever form you used last in that vault — each vault remembers its own. Or pin one form and always get it. Or turn it off and let CDD choose, as before.
• Forms your vault adds later show up at the bottom of your order, and a pinned form that a vault doesn't have leaves CDD's own default alone.

2026-07-10

No more bouncing off "you forgot the project" at the bottom of the form.

• The Project picker now also sits right next to the Create Entity button. On the *Create a New Entity* page the project dropdown is at the very top of the form, a screenful away from the Create button at the bottom. There's now a second copy of it directly left of Create Entity. Both are the same field — change one and the other follows.
• Create Entity stays disabled until you pick a project. While no project is selected the button is greyed out ("Select a project first") and the project dropdown is highlighted in amber. Nothing is lost when you forget — CDD just rejects the submit — but now you don't make the trip at all.

2026-07-08

Plates get the full treatment: locations at a glance, one-click export, and structure previews on the Plate Map.

• See where every plate lives, right in the Plates list. The Explore Data → Plates table now has a Location column next to the plate name. Each row shows a small spinner and the inventory location (e.g. Lab 1 > Fridge 1) appears as soon as it's found — no need to open each plate.
• Export all plate locations from the Plates tab. A new "Export Plate Locations (CSV)" link sits next to CDD's own "Export Plates". It walks through your entire plate list (including pages you haven't opened) and downloads a spreadsheet of plate names and locations, sorted by name — handy for a walk around the lab. If you've typed something into the plate search box, only the filtered plates are exported. You'll see live progress and can cancel at any time.
• Hover a well on the Plate Map to see what's in it. On a plate's Plate Map (and on heat maps), hovering a well now shows a bubble with the entity's synonym and its chemical structure — the same preview you already get in the inventory "Pick Location" grid. And as you move around the plate, the neighbouring wells (2 in every direction) quietly load in the background, so the next preview is usually instant.
• Everything shares one cache per browser session: a structure or location loaded once — in a tooltip, the list, or an export — never loads twice.

2026-07-07

The sample title is now click-to-copy too.

• The title at the top of each sample in the Samples tab (e.g. IXX-NUC-0000009-001-SM003059) can now be clicked to copy it to the clipboard, with the usual green flash.
• Clicking the little collapse/expand arrow still just collapses the sample — it won't copy.

2026-07-07

Click-to-copy now works on samples too.

• You could already click an entity or batch field value to copy it. Now the same works in the Samples tab: click a sample's Sample ID, Current Amount, or Location in its header to copy it to the clipboard (with the usual green flash to confirm).
• Only the header values are clickable — the labels and the event rows below stay as they are.

2026-07-07

Fix: the child-sample batch bar now actually shows up.

• In 9.1.0 the "Create N Samples" bar never appeared in the "Create Sample from Debit" dialog because it was being detected the wrong way. It's now recognised correctly, so batch creation of child samples works as intended.

2026-07-07

Batch creation now works for child samples too.

• When you create a child sample (an aliquot) from a parent sample's debit event, you can now select several positions in the "Pick Location" grid and create all the children in one click — exactly like the existing batch create. The first child goes through CDD's own Save; the rest are created automatically at the remaining selected positions.
• CDD numbers the child samples itself (SM003107, SM003108, …), so there are no duplicate names.
• Keep in mind each child debits the parent by the amount in the form — five children at 0.05 L each take 0.25 L from the parent. If the parent runs out, the affected positions show an error in the results panel and can be retried.

2026-07-06

Fix: page no longer freezes in "Pick Location" boxes containing very large molecules.

• The well tooltip draws each compound's structure in the browser. For very large molecules (long peptides, polymers, macrocycles) that drawing step could run essentially forever and freeze the whole page. Structures with a SMILES longer than 250 characters are now skipped — the tooltip simply says "Structure unavailable" and everything else keeps working.

2026-06-30

Firefox fix: batch sample creation now works.

• Fixed a crash (TypeError: formData.entries() is not iterable) that occurred in Firefox when using batch sample creation. Firefox wraps FormData iterators in Xray wrappers that strip the standard iterator interface; the extension now uses forEach instead of for...of to work around this. No change in behaviour on Chrome.

2026-06-29

Create many samples at once, and colour-code your inventory.

• Batch sample creation. In the "Pick Location" grid you can now select several empty wells and create all the samples in one click ("Create N Samples"). The first sample goes through CDD's own Save — so nothing is created unless CDD itself succeeds first — and the rest follow automatically. A small floating panel shows a ✓ or ✗ for each position and lets you retry any that failed, then refreshes the page when everything's done.
• Spreadsheet-style well selection. Pick wells the way you'd expect in a spreadsheet: normal click to select one, Ctrl/Cmd-click to add or remove individual wells, and Shift-click to select a whole rectangle. Occupied wells are skipped automatically, and a little "N positions selected" toast confirms what you picked.
• Tidier Create Sample dialog. The footer was redesigned to match CDD's own look: it shows the selected well (e.g. "D2") with the full location on hover, or a preview of the wells when several are selected.
• Fix: correct grouping prefix for long sample codes. Sample-ID prefixes are now detected correctly even for longer codes whose project name itself contains dashes (e.g. PHA-0265229-001-S001095), so colour-grouping and labels line up the way you'd expect.

2026-06-28

Colour-code your inventory by sample prefix.

• Sample IDs are grouped by their prefix (e.g. IXX-DEMO), and you can assign each prefix a colour. Occupied wells in the "Pick Location" box grid are then tinted by that colour, making it easy to spot which samples belong together.
• Prefixes you come across are discovered automatically (without a colour) so they show up in the settings ready for you to colour them.
• Manage everything under Settings → Visualization → Prefix Colors in the extension popup; colours update live as you change them.

2026-06-27

Export every plate's location to a spreadsheet.

• A new "Plate locations" section in CDD's Export dialog downloads a CSV listing every plate in your current search results together with its inventory location — handy for walking a plate list around the lab.
• It covers the whole result set (not just the page you can see), shows live progress, warns you before very large exports, and can be cancelled.

2026-06-27

See where a plate lives, just by hovering.

• Hovering a plate link in the search results now shows a small bubble with that plate's inventory location (e.g. Lab 2 > Fridge 2), without having to open the plate.

June 2026

Structure previews when picking a location, plus store-compliance cleanup.

• In the "Pick Location" box view, hovering an occupied well now shows the molecule's structure image and name right in CDD's tooltip. Opening a box pre-loads the structures in the background so they appear instantly.
• 8.2.1 is a behind-the-scenes cleanup to pass Firefox add-on review (no visible change for you).

2026-06-26

8.1.0

Less clutter. CDD now hides depleted samples on its own, so the extension's duplicate grouping was removed. The depleted-sample strike-through and the consumed-batches collapse still work as before.

2026-06-16

The Sample Panel grows up.

• Choose exactly which fields the Sample Panel shows — name, location, purity, internal ID, density, concentration, solvent, weights, batch, vendor ID, owner, amount, volume — all toggled in the popup.
• Automatic custom-field discovery — vault-specific fields (like *Hygroscopic) are detected from your data and offered as checkboxes.
• Paste-ready concentrations — clicking a concentration copies a normalised, CDD-friendly value.
• More reliable copying everywhere, even on restricted pages, with a clear error state instead of silent failures.
• Printing now follows your chosen fields, plus a round of internal cleanup.

May–June 2026

7.x

A steady stream of quality-of-life improvements:

• ELN tab titles you can customise (entry ID + title, title only, or original).
• Sample Panel remembers its position and collapsed state between visits.
• "Copy Link" on saved searches for quick sharing.
• Consumed batches collapse into a tidy, togglable block.
• Broader recognition of Purity / Density / solvent field variations, and a responsive multi-column layout for molecule links.

May 2026

5.x – 6.x

• Smart filter defaults — automatically picks a useful filter operator instead of "Any value".
• Resizable location-picker tree — drag to set the width, and it's remembered.
• Various location-picker and molecule-link layout refinements.

April 2026

3.x – 4.x

• Dose-response "Easy Override" — bulk-adjust curve calculations (max / min / skip / don't overwrite) straight from the search results, written back to CDD.
• Click-to-copy fields on molecule, property, and batch values.
• A series of file-dialog and layout fixes.

March–April 2026

1.x – 2.x

The beginning. Core stoichiometry tooling, the depleted-sample marker, solvent and internal-ID handling, and concentration-unit normalisation. The extension was renamed to "CDD Stoichiometric Table Tools" to reflect its growing scope.
