Undo lists the currently available undo one step back. Much different than history.
Problem is, not everything is captured in the undo stack and likely wouldn’t be listed in a history as regards reverting to a point in the past before that, either.
I would be happy just for an actual Revert…but a history panel where all actions are listed wouldn’t be a bad addition.
As Bhikkhu Pesala’s screenshot shows, Undo displays a stack of undo steps. Having worked with history panels in other programs, I do prefer them, but I think Undo/Redo stacks work reasonably well.
