Jetbrains’ IDEs have both of them and more. The feature is called “Local History”. [1] You can see the history of an file, a selected region of text, or even your entire project. It can undo file deletions/moves/renames. It feels like a personal “automated git without the git hassles”. It has got me out of some really bad situations.
