Hey Matt,
There is currently no de-bugging available for anything schema related, however @mark has shown off a few pics on discord and he is very close to having a finished real time editor made.
The best thing to do now is make the app with out schamas then add them in when its finished and just explain during your Pull Request on Github what it looks like and what its supposed to do. In all honesty id just wait for MArk to finish he is really freaking close to being done.
