Undo a check-in or check-out pressed by mistake

In this video

1. Did the receptionist press Check in by mistake for a guest? No problem.
2. Within fifteen minutes, an Undo button appears right on the booking, showing until what time you can undo.
3. Click Undo: the booking goes back to Confirmed, and the room is still held for the guest.
4. Undo works for check-in, check-out and no-show, and each is recorded in the log. Cancelling a booking cannot be undone, so the system always asks again before cancelling.
