Wanted to pass along a case study of some work being done to improve the look and feel of IDLE. This is a work-in-progress, gradually being integrated into the Python codebase. Given that, it's a great opportunity to get involved, provide some feedback, and make it even better!
http://www.tkdocs.com/tutorial/idle.html As you can tell from the URL, it's part of a broader tutorial on modernizing the appearance of Tkinter based programs. Mark -- https://mail.python.org/mailman/listinfo/python-list
