I don't know, all of those are pretty similar to me.

I'd like to be able to develop in other languages the way I do when I dabble in Pharo, i.e. mostly windows and widgets and dialogs that abstract away boilerplate, file and directory management, and allows me to relatively easily extend the environment when I feel like it.

Instead I tend to complement the editor or IDE with a rather large set of Linux and Unix programs in terminal emulators. It's not nice or easy to teach, but nicer than trying to figure out whatever module protocol used by the editor. Perhaps I could have stayed with Emacs and been content, but when I arrived at this methodology Emacs was still single threaded and quite sluggish in comparison.

I'm hoping Glamorous Toolkit might be the thing that eventually grows into what I'd like to have.
