The app does look nice, though I can't really test it (since I'm avoiding -Testing/-Devel, had to reflash once already). However, I have a minor suggestion. Add support to modified Hildon Home. If I recall right Matan's modified HH supports up to 9 desktops and thus this app would be quite great to allow support to more than stock 4 desktops.
