I think it's fair to say Smalltalk(s) have had in many aspects the most advanced IDE in existence at every moment since its introduction.
Demos for a couple old versions: https://www.youtube.com/watch?v=NqKyHEJe9_w Demo for Pharo: https://www.youtube.com/watch?v=baxtyeFVn3w
Not only Smalltalk, all Xerox PARC Workstations
Interlisp-D, Mesa (XDE) and Mesa/Cedar, all shared same ideas with Smalltalk, regarding developer tooling.
Same on Genera with Lisp Machines.
