I hate to ask this, but what happens if you want to play another character from that which you have selected in the installer?
gm9 has made some class detection code that he uses for his quick access buttons which means the buttons change automatically depending on what class you play. Maybe a quick chat to him to find out how he does it. Would make the UI easier to use if you have to load the installer every time you want to camp to another character
Apart from that, I think it is looking great. I especially like the graphics of the chatwindow. It feels completly different
