Moar! Rated 5 out of 5 stars
I really like it, but anything gets boring after a year. Moar skins, moar! Or - could a system like Bookmark Favicon Changer's let users apply their own? Hey all you creative people out there! I did just discover CustomAppButton though; so far, as a non-css'er, I can at least get rid of those boring letters - also pretty cool.
