I'm interested in this but the project has been stale for 9 months.
and I'm not sure to use it or not.
(Besides that I I have trouble getting it working.)
I want to use it in production, all thought I might contribute if needed, I just need a python editor that works in a formPanel (where a text area should be a form field)
I have tried CodeMirror but I run into lots of key mapping trouble (space amongst others makes the editor loose focus.
FYI, There will be some updates to the project and more instructions on how to use it in the coming months. I cannot support the existing code as things are going to change a bit.
