Great point.  It's actually fairly easy to do in matplotlib: you can
just make your "event manager" routine record a history of events,
e.g.:
self.event_history.append(event)

and as long as you have one overarching event manager for the GUI
(which is probably an important design decision...), it should be able
to track
exactly what has been done and repeat it.

That said, events can be tied to individual axes, so if a window is
closed, it would be essential to re-create that window in the same
state it was originally initialized.

Anyway, 2 cents on GUI design...
