This is very good. I like how the menu button changes to show you the number of diggs.
I think it would be nice if you had a toolbar button that looked like the digg button and showed the number of diggs. Also if the site wasn't dugg yet it would say 0 and you could click it and it would take you to submit it to digg.
That's just my thoughts.
