Are sure about that? Is it not Pharo Preference system you are referring 
to? Because what I see in Squeak is the same things as in Cuis. Cuis 
obviously inherited from the Squeak system. The only notable difference 
I see is the use of pragma to annotate methods providing Preference.

I have used extensively the Pharo preference system for DrGeo 
preference. It is very capable, a bit complex.
