I am refering to the drawing itself. When it comes to using undo, I am
sure you could feed data into helm (or other completion system) and
have a list of branches with fuzzy completion instead of graphical image
which probably would be as usefull or even more useful that graphical
tree. But as I said, I think the graphical representation itself is cool
and as you describe, for some users more clear option. I just undo with
M-x undo, in my case it is bound to C-_ and works just fine for me.

Sure, whatever works. I didn't yet have encountered such case for
myself; I tried undo-tree some years ago and uninstalled it since I
never used it.
