Well, since you're working on the launcher anyway, may I post two of the smallest suggestions ever?
1. The dark blue text saying that you'd wait for the client to patch itself is almost unreadable on black (atleast for me it is) so maybe it could have a slightly brighter colour?
2. all the links open in IE, is it possible for the launcher to detect the default browser and open the links with that?
Both suggestions don't really bother me as I know what to do and the forum is my startup page anyway, but maybe it would nice if it could be.
Grtz
