Interesting stuff.  If Morphic 3.0 is advanced enough it might be possible 
to make a very advanced window manager right in Squeak.

What made me think about it was your explanation of Morphs being able to 
answer if they are in a point or not.  I was thinking in the case of a bunch 
of windows stacked on each other you could mouse over, click some command 
and the pile comes to the front to show what all is in the area (kind of 
like what I have seen people do on a Mac).
