As an educator, I appreciate the decision to bundle libraries such as PyGame, Matplotlib, etc with the editor. Although it's important for new coders to learn how to install libraries, it doesn't need to be one of the first things they learn. It's really nice to be able to install an editor, show students a few lines of code, and have it do something more than just print some text to a terminal. (Although, for the record, printing text to a terminal is still immensely satisfying to many new programmers. It makes them feel like they're really programming.)
I've been teaching programming off and on for many years, and I'm teaching another intro course this fall. I can't wait to give Mu a try with students.
Thanks for all your hard work, and the clarity of thinking that's gone into this project.
