Currently it’s not possible in the Designer to tell if a resource like a View, Template, Window, etc. is overridden from an inherited project, or if it’s just a new resource that was created inside an inherited resource folder.
Case in point:
Is this Main Window part of both the inherited project and the inheriting project where it’s overridden? Or does it only exist in the inheriting project?
I’ll give you a hint, it’s the latter.
