Feature request Undo last save.

[DanaMW]

Hello friend I hope the new year finds you well. I often get to saving so fast i hit the wrong folder so i thought i would request an " Undo last save". Truthfully a Move last save might be just as useful but that move could be done with a delete and re-save. Tracking down a single misplaced pic can sure be a pain in our large data bases. Thank you,
