Rated 4 out of 5 stars

Hi Paul!I think it doesn't introduce instability or something else: actually, it's just an interface extension, showing something in a different way. It doesn't store data, execute hard calculations or anything else. Eventually, I think I'll take a look on XUL language (they say it's not much different than Javascript) and will as Jeroen to help him in mantaining this useful extension :)
