What I really want is something that can cause the icon to change when I get new chat messages. I frequently find myself unable to hear the soft incoming message sound, because I'm listening to something louder, and it would be nice to have a visual indicator.

I use this Greasemonkey script to do this. It works in Chrome and Firefox:

It does the unread count thing, but it also toggles between it and the chat icon if you have unread chat messages. It's a must if you pin gmail tabs.

I've been using this script all day, and it's been great. Thank you so much.
