Undo Tree selection mode doesn't work with Evil
Undo Tree's selection mode allows one to navigate the undo tree without changing the parent buffer. This is most useful when doing a diff between distant nodes with Undo Tree's
\s command. Ctrl-Z to evil-emacs-state and navigate the undo tree, observing the parent buffer doesn't change. Ctrl-Z back to evil-normal-state and navigate the undo tree. The parent buffer changes in the same way as when selection mode is disabled.
