Vim has plugins for that. ;)

I use https://github.com/mbbill/undotree but if that's not to your taste there are many others.

F** right off. How have I used Vim for fifteen years and not learned about this.

Haha, that made me spit my drink. :D

I rarely have to use it, but Undotree is so amazing when you need it.

I don’t doubt that IntelliJ overall is more user-friendly. But just to note, Emacs’ undo-tree can also show the diff for each change.

Visual Studio Code offers something similar in the timeline view. It's not as fine-grained, but still can be a life saver.
