Your project boards, one keystroke away — not one browser tab away.

Only the half that one person actually uses. Boards, columns you define, labels, checklists, due dates, archive and export are all there. Collaboration, comments, attachments, automations, power-ups and gantt views are not — and they are not "coming later" either, they are the definition of the product. A board you share with a team needs a server, an account and an invite flow; this one needs a keyboard shortcut.

Yes, from the JSON export you download yourself — the widget never talks to Trello's API, so there is no login and no token. Lists become columns in their original order, archived lists are dropped but their cards are rescued, closed cards are archived or skipped depending on what you choose, label colors map to the closest one in the palette, and card checklists and due dates come across. What the widget does not model — comments, attachments, members, stickers, custom fields — is discarded, and the import summary tells you so instead of pretending it arrived.

Yes, and that is the part a browser tab cannot do. Each due date is scheduled in the app's native layer, not in JavaScript that only runs while the widget is on screen, so the notification arrives with the popover closed — and it survives restarting the app, because the scheduling code loads eagerly rather than waiting for you to open the widget. Imported dates are the deliberate exception: they come in without being scheduled, so importing a year of old Trello cards does not fire forty notifications nobody asked for.

It is a JSON file on your machine, and the export writes exactly that. The import merges by id at two levels — the board, and the columns, labels and cards inside it — and never overwrites what is already local, so re-importing a backup adds what is missing instead of rolling you back. There is also a one-way Markdown export for pasting a board into a document.

To tell you that a column is overloaded, not to stop you. Set a limit on "In progress" and the column header turns amber when you go over it. It never blocks a card from moving: a tool that refuses to let you write down work you are already doing just gets a board that lies.

It fades and says how many days it has been sitting there. Card aging is on by default at 14 days and you can change it or turn it off with a zero. Cards in the column you marked as "done" never age — being finished for a month is not the same as being stuck for a month.

Not in one click. Cards get archived before they can be deleted, and deleting from the archive takes two steps. A column that still holds cards cannot be deleted until you say where those cards go — the alternative is a delete that quietly takes work with it.

If you turn it on, per widget. Toolbox ships a local MCP server, and this widget exposes 18 actions through it — list boards, add cards in a batch, move one, set a due date, edit a checklist, manage columns and labels, archive, export. It is off until you allow it, and a batch of cards is a single write, so one undo takes the whole batch back.

Yes, in the system tray, same as on macOS in the menu bar. What it does not do is run on the iOS build of Toolbox: this one is desktop only.

Yes. Webstarted Toolbox is a free beta and needs no account, and Project Boards is a free widget in its catalog — one click from inside the app installs it, with no app update needed.
