Hey that's a good suggestion!  Really different from anything else I've ever
seen though.... Also I'd rather see finer granularity on the Undo -- maybe we
can treat "Apply" as creating a checkpoint and each "Undo" goes back one more
checkpoint.  So the following would work:

initial_state.
change1
Apply
change2 change3 Apply
Undo [reverts to initial+change1]
Undo [reverts to initial_state]

Close would be active after either an Apply or an Undo (only inactive after a
change.)
