I was wondering if undo-tree is only there to match Vim behavior, and if I could use Evil without it. I actually find built-in Emacs undo functionality intuitive and I'm used to how it operates. On the other hand, I've run into some cases where undo-tree didn't behave as expected. If there are no ill consequences in using original Emacs undo vs undo-tree, it would be nice if it were configurable.
Undo tree is completely optional, but if undo tree is available and already loaded, the undo command "u" is mapped to the undo function of the undo-tree package. If you install evil via el-get undo tree will be loaded automatically. But you can get the old behavior by remapping "u" do the standard undo function: (define-key evil-normal-state-map "u" 'undo) and if you have the redo.el or redo+.el package (define-key evil-normal-state-map (kbd "C-r") 'redo) Frank PS: just grep the sources for "undo-tree" and you will see that evil guards everying with something like (when (fboundp 'undo-tree-undo) ...) overriding the default bindings if the undo-tree equivalents are available. But you can easily "undo" these changes to undo ;)
