@amdt I started #Smalltalk with Squeak, then Pharo for many years, and now I am using Cuis. Cuis is a craftsman job: clean, coherent and easy to understand. Its GUI Morphic has been vastly redesigned to be coherent and much easier to use. I like it very much. There is the VectorGraphics system written in Smalltalk (no external library). See my recent post on the experimental circular toolbar.
