That might be a good addition, indeed.

Sounds very difficult.  Maybe we could simply highlight the newly
modified text somehow.

And maybe we could additionally provide a "undo-slow" that would first
highlight the about-to-changed text, then wait a short little while, then
perform the undo and highlight the new text (and maybe even highlight the
"next text to be undone").
