After most actions that move or remove plans, an Undo link appears at the top of the page, just below the planbook title. Click it and the change is reversed.
Undo covers the things most likely to go wrong:
- Bumping a day or a period
- Clearing a day
- Moving or copying a day
Use it straight away
Undo is tied to your current session and to the action you just took. It isn't a full history you can step back through — it's there for "that wasn't what I meant," immediately after the fact.
If you sign out, or your session expires while you're away from the computer, the undo goes with it. So if you spot a mistake, take it back before you carry on.
When there's no Undo link
For a plan that's already gone — deleted a while ago, or a session ago — see Recover deleted plans. Deleted plans are kept for three days and can be restored from the Cubby.
For an edit to the text of a single plan, there's no undo. Reopen the box and retype it, or check whether an earlier version is in your Cubby.
The safest habit with a big restructuring — reordering periods, changing the rotation — is to copy the planbook first. Undo is for single actions, not for reversing an afternoon's work.
