Interesting. So far I have only thought about how Cuis could support 
stuff meant for Squeak!

WRT compatibility of apps with Squeak, I believe Cuis packages will fall 
in 3 categories:

1) Stuff that is identical (almost) to Squeak. For example, I took the 
current Compiler categories and  Kernel-Methods to support closures. 
Kernel-Classes, Kernel-Objects, Kernel-Numbers and all Collections- 
categories could follow. These are parts of the system that are in good 
shape in Squeak, and have people doing great work there too. Stuff I 
can't really improve.

2) Stuff that I have somewhat modified. I removed lots of protocol. This 
obviously doesn't affect porting Cuis apps to Squeak. But I also removed 
arguments, making some messages shorter, and added some convenience 
methods. This is easy to address by adding an optional 'Cuis 
compatibility' package for Squeak.

3) Stuff that is really different. For example TextStyle, and the new 
TextEditor application. (I'm not talking about the Editor hierarchy 
here. In Cuis do World/Open/Text Editor. I also have a fairly complete, 
not yet released, style based text editor.) These might need being 
ported to Squeak and will give some work. I could also include Morphic 
here. But I also hope to replace the current Morphic in Cuis with 
Morphic 3. And I also hope to be able to make Morphic 3 an optional 
package for Squeak and Pharo.
