Sorry to resurrect a very dead thread, but for anyone who may still be interested in this project I have decided to broom it and see if I can get it working again. The branch (still WIP) is here.
Already it’s working with python 3 and latest build of the panda libs, and most of the breaking issues are resolved. I can’t guarantee long-term support because I have different priorities for doing this over and above building an editor for the sake of it, but someone might get some use out of it.
