I switched back from undo-tree to undo-fu, which re-uses the emacs undo-system instead of replacing it and makes it more intuitive to use while still preserving the full undo history. I sometimes miss the nice visualizations such as the tree and I didn't even know (or remember) the diff, but in 99% of cases I just need simple undo and most of the time I have git anyway to save intermediate states of my files.
