People, chill. You cant ask everythin' from just a plug-in, you know... I agree that those features with close button and font/color should be improoved, and when pop-ups go away it should not just disappear but also like "fall down" like MSN 6 ones, and a lot of other shit, but this's really not the reason not to have it installed
And yo, Xerxis is away 'til September, so there will be no update for like a month.
Just be happy with what little we have
