+~undo-tree~ is my preferred way of undoing and redoing stuff. The main
+reason is it doesn’t create a linear undo/redo history, but rather a
+complete tree you can navigate to see your complete editing history.
+One of the two obvious things to do are to tell Emacs to save all its
+undo history files in a dedicated directory, otherwise we’d risk
+littering all of our directories. The second thing is to simply
+globally enable its mode.

+An interesting behaviour from DoomEmacs is to compress the history
+files with ~zstd~ when it is present on the system. Not only do we enjoy
+much smaller files (according to DoomEmacs, we get something like 80%
+file savings), Emacs can load them much faster than the regular files.
+Sure, it uses more CPU time uncompressing these files, but it’s
+insignificant, and it’s still faster than loading a heavier file.
