Add a Tab to Another Canvas

Reuse a tab elsewhere: add the active tab to another of your canvases, and edits made in either place appear in both.

Sometimes a tab you built in one canvas belongs in another too: a glossary, a shared timeline, an architecture board two projects both rely on. Add to Another Canvas adds the active tab to another canvas you own, without leaving the editor.

Adding a tab to another canvas

Open the tab's menu (the ⋯ button on the active tab, or right-click the tab).
Choose Add to Another Canvas.

In the Add to Another Canvas dialog, pick the destination. Each canvas shows as a tile with a preview of its canvas, and the filter box at the top narrows a long list. A message confirms when the tab has been added.

The option is greyed out when there is nowhere to add the tab to: if this is your only canvas, until you create another, and in a canvas in This Browser. It isn't offered to Viewers or Participants, or on a link shared for one tab.

Add to Another Canvas opens a dialog of your other canvases, each with a preview of its canvas, and a filter box to narrow the list.

One tab, shared between canvases

Add to Another Canvas doesn't make a copy: it is the same tab in both places. Edit its elements, restyle it, or rename it from either canvas and the change lands in the other as well, a few seconds after you stop editing. If the other canvas is already open in another window, reload it to see the latest edits. If the tab is edited in both canvases at once, the later edit is the one both keep. A tab can be in up to 20 canvases at once.

Two things stay per-canvas, so each canvas can organise the shared tab its own way: the tab's position in the tab bar, and which tab folder (if any) it sits in.

Removing the tab from one canvas doesn't touch the others; the tab and its contents are only deleted for good when you remove it from the last canvas containing it. Deleting a whole canvas works the same way: while it waits in the Trash its shared tabs stay in step, and once it is deleted for good they stay, with their contents, in every other canvas they are in. Taking a canvas offline tells you first how many of its tabs are shared: they stay in the other canvases, and the copies in this browser stop sharing edits with them.

Prefer an independent copy you can tailor per project? Use Duplicate in the same menu first, then add the duplicate to the other canvas.
