I agree that GUI programming shows OOP to its best advantage. I am just 
not convinced that this is the only way to do GUIs. I also have never 
liked the over-reliance on physical metaphors associated with teaching 
OO. Objects are an abstraction mechanism, but students don't learn to 
deal with them in that fashion.

At any rate, these topics are fodder for one or more PhD theses, and I 
don't mean in any way to complain about the underpinnings of a tool 
which has been so useful to me. Refactoring MrEd has got to be way down 
on the list of priorities. --PR
