Found out that the Gnome Guys have resources to mock up UI designs for GTK applications. I figure it would be a great tool to use to mock up designs for the Perspective Mode that is currently being worked on. Plus it could be useful for those submitting Feature Requests for MyPaint itself, or at least help keep the UI consistent.
Speaking of which we should provide our own mock up templates for MyPaint that don’t exist on the standard Gnome Set.
