Setting / Background : added backgrounds are too easy to delete/remove
GCC / Setting version 3.36.x :
Pictures added manually when you want to use a custom background are too easy to delete/remove
If you, accidentally, press the remove round button ( on top/right thumbnails' corner), the picture is immediately deleted without move it to trash..
Imo, should be better show a user confirmation specifying that the picture will be permanently removed or change the behavior of this task moving the picture to trash instead of removing it immediately.
