Semi-related: What I really wish all my editors and IDEs would have is some kind of "delete history" view into my deleted text (especially blocks of text).
I'll often delete something, then work for a while, then realize I need that thing back again so I have to VERY carefully undo everything after the delete until I get to a point in history before it, copy the deleted text, then re-do everything back to my original state while making sure not to accidentally execute any inputs which would burn down the redo stack.
