Provide revert/history/undo feature #22
Description
If you accidentally overwrite a value in a field, there is no way to undo it. Since the back gesture automatically saves the record, the only recourse is to retype the original value. In some scenarios, that could be quite a pain. Perhaps a menu item to cancel the current edit?
It's more complicated than that. The "correct" behavior is to save the item whenever any of the fields change. Believe me, that's the behavior that you want -- otherwise you lose your changes when the lockout timer fires (right now, creating a new item requires an explicit save, and I've been bitten by the timeout several times).
I'll file a feature request for some sort of history. That one's going to take some deep thinking, since it's not clear what should constitute "a single edit" when an item might be saved multiple times in the space of a minute. Furthermore, keeping history around will balloon the database, which will make the app slower and more error prone. An automated full database backup combined with the ability to selectively restore might be a better solution...
