Selectively Running Tests

Hey all,

My goal is to build a UI that will present a tree view of all my available test suites/cases and allow the user to choose what tests they want to run.

I need a push in the right direction as to the best way to start programmatically building out partial test suites while preserving all the great metadata funtionality in my test cases that FU4 adds. Any suggestions?

Thanks!
Brian
