2 years ago, Adobe programmed that the Tags panel would have Undo. That was very helpful.

But we also need to Undo in the Order and Contents panels, too.

When remediating PDFs to meet accessibility guidelines and laws, people work in the Order and Content panels, too, not just in the Tags panel. As in any workflow, we sometimes need to undo what we just did.

Right now, we must revert to the previously saved version which might go back too far and not be helpful at all.
