Ok, first observation I have is that it's designed for a screen that's bigger than 10"

I'd love to see the player list on the side, and perhaps even the chat on the side, as it stands I can sort of chat but I can't kick or anything.

I'd also love it to save the window layout on exit - after resizing the lobby so I could see the games and players, if I quit and come back it's back where it was.

and of lesser importance - upnp support
