Thanks juan. You conclusion is good and I'm happy that we made it that way.

> 4) Some of the ideas in Morphic 3 are novel enough that I need to protect them from being patented by others from, before disclosing them. I don't like software patents, so I believe the best way to do this (and get more people to know these ideas) is to submit a paper to a journal such as ACM Transactions on Graphics. This will obviously require additional time.

I believe that many in the Pharo community share my opinion that the current Morphic implementation is obfuscated, that it is too hard to write applications with it, and that it is too hard to fix bugs and evolve it.

I think it could be of great value for Pharo, and an enabler for evolution. So, I did a request to Esug, to deliver this, naming it "SimpleMorphic", ready to run in Pharo, instead of Morphic 3. Esug approved it, and I thank them for this. SimpleMorphic is the result of this. I started by extracting the Morphic in Cuis. This was not trivial, as I had to think carefully where to draw the line between what I'd migrate to Pharo and what I'd use from Pharo. Then I adapted it to some differences between Cuis and Pharo, and also tweaked Pharo to enable using alternative UIs. I worked about 80 hours on this and delivered this week.
