Nice approach.    Is any of this code available for previewing anywhere?

I agree;   Additionally, many times, even if you have a native API,
developers go out of their way to differentiate their UIs by creating
custom widgets and custom controls to improve the user experience for a
specific application, so they end up different.

Additionally, a collaborator has created a small "bundler" that we are
planning on integrated into Visual Studio, the idea being that you can
go from Visual Studio to a Mac-accessible DMG file that you can
