But there is the crucial difference that in regular IDEs you just manipulate text files. A text editor is a valid alternative for that. In Smalltalk, the GUI manipulates objects in memory. A text editor can not do that.

Precisely. A couple of the IBM Smalltalk people went on to create Eclipse. The product name for IBM's Smalltalk was "Visual Age". That Smalltalk originally came from OTI.
