I think this app is just wonderful, it look great and is faster that starting Preview. It add's a nice mirror effect too wich will surely impress your non OS X friends. The only thing I'd like to see changed is that the app remains in the dock. This kind of app should not appear in dock, it clutters too much and has no use to be there. Instead make it a background app with maybe a pereference pane. Keep up the good work though.
