Since I typed up an idea on Undo, I figured I should report this too.
when you use Undo and that Undo has incorporated removing folders you just recently added, and then you realize it and redo at least to that point of putting the folders back, or whatever reason you may need to do the Redo and it incorporates folders, it does not return the name you gave it, it puts it back as if you just created it as “New Folder”. The contents inside will all be there if you put something in it and did the redo that far, but the name never goes back.
