Yeah, that was a smart move, wasn't it?

I quite agree.

I remember being extremely surprised to read that a Python developer I
greatly admire uses IDLE as his main development interface. Frankly I
have always found IDLE extremely non-intuitive, and I am constantly
frustrated at having to explain about its shortcomings and oddities to
newcomers in my "Introduction to Python" classes.
