Thanks!

I was aware of your opinion wrt. Morphic vs. MVC. I think it would be 
very interesting to see someone take MVC to the level of mouse based 
interaction that Morphic already supports.

Well, the real question is: Is Sparta/Block/Brick lighter than Morphic? 
Would it give better performance? I guess someone has to try.

I believe it was John Maloney who once said that even the little dot on 
top of the 'i' should be a Morph. Still, in Morphic, a text editor is a 
single morph, as you say, for performance reasons. Perhaps a morph 
supporting music notation could be built in a similar way, or perhaps a 
middle ground design, where each staff is a morph.

I wonder if in MVC or Brick having an object for each note would give 
good performance, or at least any better than Morphic.

Just thinking out loud.
