How do I sort, rename or remove entries in the sidebar?

Via the ⋯ menu on each entry, or by drag and drop. If you drag an entry onto another one, it then sits inside it. Removing deletes only the shortcut, never the app or the data behind it.

1. 01⋯ → “Rename”, “Move up”, “Move down” or “Move to …”.
2. 02⋯ → “Pin” places the entry at the top under “Pinned”; “Unpin” takes it out again.
3. 03Owners and admins can put an entry into the company's navigation with “Share with the company”.
4. 04By keyboard: Alt + arrows moves or nests, F2 renames.
