Just thinking that instead of chat being embedded, perhaps making it selectable from the top of the page (like stable, arena, forum etc) and opening a new window would be the way to go. That way people could opt to be in chat or not, and allows people at work to look less suss when they just have a chat window open. I would imagine that a dedicated window would make it easier to navigate once multiple channels are introduced. A bonus would be that chat doesnt need to be resized all the time when changing PoW window size (i often swap between full and 1/2 screen web browser windows when multitasking, and it warps chat something fierce)

oh, and being able to nominate from a variety of text colours would be cool. it'd make it much easier to tell people apart in chat
