As the guy before me said: If you edit scenes and pack your own .vars, this seems very helpful. UI is ... kinda primitive, but you make it work, and if one is used to had-editing .json files, it's OK.
The plugin is helpful ... your waving around a mousecursor like a deafmute, not so much. You're a technical creative with very good ideas and superior skills. Get (the fuck!) used to explaining your ideas and intended workflow. And please use common terminology - it's "an updated version of the package", not "The [1->2] case".
TL;DR - Shut up and take my money!
