Undo Tree is a neat visualization and navigation Emacs Tool for walking through a tree history.

If I make a mistake I can visually navigate the history of the work by hitting C-x u and navigating the history of the document visually. This is a feature that I don't use often but it's super useful when I do. More concretely this package provides a useful and reliable redo which it binds to M-_ a sister-key binding to C-_ and it's also used by Evil Mode's undo key u and C-r for redo. C-x u will show the history tree for exploration.

It's simple and having it around is cheap and easy.
