Plugin Request: Theme Showcase w/ Supporter

I like the concept of the ThemeBrowser plugtin. It allows you to showcase the themes you offer on your site with thumbnails inserted via shortcode. Very cool.

This makes a lot of sense as someone thinking of signing up to blog would probably want to see their theme choices first.

But it doesn't show "Supporter-Only" themes.

It would be great to be able to showcase on a page both the free and "supporter" themes.
