I love the UI, it's literally perfect. However, I prefer to have a few adjustments:
1) Is there a way to add/remove Sidebar Gadgets like you can in the real Win7?
2) The ability to remove the YouTube, Flickr, and Twitter apps?
3) How to add/remove desktop icons?
4) The program could use a full-screen button, that way it can overlay over the host PC's interface.
Great job otherwise!
