a few more suggestions

> 3 - enable me "tear" an item away from the main program and make it "stay on top" and resizable so that I can easily take notes while watching a video. Right now, I have to use a "post-it" program, which doesn't integrate nicely with URP4. When I'm done, of course, I'd like it to appear in the correct spot in the Explorer pane.

I endorse this one. I also use a post-it program for the same reason. If I want to take a note on another item within UR, there's no easy way to do it. OneNote, for example, has Side Notes for this purpose.
