[Feature] Duplicate detection "back" buttons for mistakes, and correct aspect ratio's

I have searched the existing feature requests, both open and closed, to make sure this is not a duplicate request.

• Yes

The feature

lots of times, photos are cut off from the thumbnail and i have to open the photos manually to check which ones i want to keep or delete. especially portrait photos are impossible to check out without opening them first.

furthermore, sometimes when mass going through these results i make mistakes and wish there was a back button, to undo the mistake. the trash can can contain many photos and its sometimes not possible anymore to see where i was. i was also in the situation that i accidently double mouse pressed, and i skipped a entire line of photos that just 1 of, was kept because of that.
I would really like a button to go back.
