The editor is fully functional according to the design we made for AoW, the fact that you think it's the entirety of the expansion and thus should carry 20$ of content is entirely your opinion and not remotely true in our view.
That said, I'd like to expand more on flag customization options in the future. It's not as simple as just copypasting code from CK2 and calling it a day, though.
