Thanks for admitting this. Some people refuse to see the truth!

Yes. IDLE is first and foremost a tool to get work done. However we
should not ignore the fact that IDLE could also be a great learning
resource for Tkinter GUI's and other subjects. Why not clean up the
code base? We could start small. First, move the custom widgets like
textView, Tabbedpages, FindDialog, ReplaceDialog, and TreeWidget into
the lib-tk for others to use more freely. Then we can modify the
"event robbers" CallTips, ParenMatch, and ColorDelegator. Just small
steps Kevin. It all starts with babysteps. At least we would be doing
something. Currently we are sitting around waiting for a miracle to
happen, and problems are solved by methods, not miracles!

Well some changes and improvements can be made to the UI as well.
