📝Glamorous toolkit

§ Extensible system Smalltalk

Glamorous toolkit is a Programming system that is centered around object “Inspector”—it shows a customizable view of an object, it can be interacted with. Most of the work is done playing with the objects in the playground and inspectors. You write code inline and you don’t have to drop into a different text editor to do “serious programming.”

The code in GT is still pretty much text, but you only edit small portions of the code at a time, so that’s bearable even with primitive text editor.
