Missing conversation is reported

When you reopen the canvas and an agent's previous conversation is not restored, the app reports it right away and names the account it searched. If the conversation lives in another installation of the agent on the same machine, the app says which one. Previously the agent simply came back without history and without explanation.

The ⌘K hint

The hint at the top of the canvas no longer disappears on its own and now has its own control under Settings → Interface. With it off, the workspace tabs move up and take the space.

Fixes

The app no longer quits on its own when it is brought back after another program was in use, including when the return comes from a click on a system notification.

Long branch names no longer overlap the command bar: the name is shortened in the middle, keeping the start and the end, and appears in full on hover.
