When using TestLeft to test our WPF application, I have to add some composite controls to the list of things that the UI spy can see. It would be really awesome if the UI spy could remember those controls that are added when not running a test. Right now, if I am developing tests and there is an object that the UI spy can't initially see into, I have to start debugging a test, wait for it to hit a breakpoint, and then I can use the UI spy to see what I need.
If the UI spy could somehow remember all of the composite controls that were set the last time a test was run, it would make things a lot quicker and easier for me as I write my tests.
