I just found a nice app for iOS:https://itunes.apple.com/app/id984305203
It would be great to have something similar for Windows 10 as well.
I made a draft:
1. Step back. Undoes moving.
2. Shows the picture number/total pictures
3. Extra folder for files to delete (or move to recycle bin, dont know if undelete harder to implement)
4. A current picture
5. User created folders
6. Add a new folder
My hotkeys suugestions:
spacebar or swipe up - delete and move to the next pic
arrows or swipes - next/prev picture
probably xcvbnm for user folders
