I like features of IDLE3, but the shell that comes with IDLE3 is no good. Something that takes 5 seconds to run in the terminal, would crash the IDLE's shell.
So I'm looking for a replacement for IDLE3.
I looked at Geany. I like the editor, but I prefer an IDE with a Python3 shell that has tab completions for Python3 objects. Kinda like how "python3 -i" works, but "python3 -i" doesn't do tab completion.
