@zens@merveilles.town If I think of GUIs that would do many of those things well, I think of a REPL with syntax highlighting, autocompletion, introspectable and referencable outputs, etc. In particular, I think of something where every action that is available via the UI is also available to the REPL. That would be a GUI according to definition thereof, but would be morally closer to a text UI with lots of steroids. I think the closest thing to that in existence is the SmallTalk UI (but I haven't touched it in more than 10y, so I base it on vague recollections).
