When I'm on Scripting Helpers, I'm often signed into chat on the main site, but have the chat minimized (as I strongly prefer the layout that gives). It would be beneficial if an icon or number showed up telling me that someone's chatted (not entered/left, as it already tells you how many people are in the chatroom) so that I know when people are chatting and can re-open the chat box. Once/while the chat box is open, that icon/number should reset.
