You will need to create the face within the entities context of a group or component, as only they can be transformed.
EDIT: Actually Whaat might have a better idea, here:

Echoing my response here from the other thread:
Not sure about the intellisense. Unsure how Sublime handle that.
As for the debugger, I think it should work if you can find a package that let you set up remote debugging.
RubyMine only need to know/care about the lib folder in that repo. You can tell it to ignore the other folders.
As for the auto-complete, I'm having some issues right now myself. Maybe something changed with RubyMine... I'm not sure. Looking into it.
