[UI] MVP (was How can targets better track the mouse?)

[Bill Schwab]

Jason,

Rob Gayvert talked about that as part of wxSqueak - I do not know how
far he got, and I have seen rumblings about a morphic that is
wx-friendly.

If we get too many people involved, we will risk the same problems as
the Squeak community as a whole.  Too few, and we repeat mistakes and
miss opportunities to leverage existing work.

Details aside, I think MVP is the best thing since self-slicing bread,
and we would do well to bring it to Squeak.

How would it sound to start a project to bring MVP to Squeak?  I
really think a framework like this will bring us further then most
other things we could try.  And having MVP doesn't mean we can't use
Morphic for the view.
