Hi Hilaire,

I haven't had time to focus on this yet, but I agree that it would be 
great to start moving in this direction. I guess the model would be less 
powerful than "full morphic" and more focused on composing widgets, right?

I'll read the links you sent.

It some point, we could consider recoding the Smalltalk tools, if it 
would result in cleaner or simpler code.

Thanks,
