Deleting a single note via the three‑dots menu is fine without confirmation, since it can easily be recovered from the trash. But deleting an entire notebook happens just as quickly and without any warning, if you happen to click the three‑dots menu of the window, which makes it easy to mistake for deleting only a note. Although the notebook can also be restored from the trash, this error is too easy to make. A confirmation step when deleting a whole notebook would be a valuable safeguard.
