I recently switched to mac from PC and am getting used to the new interface. I want to know, other than the audio notification how can you be notified if someone responded to your chat? (ie assuming your sound was on mute) For example, in windows, i had all my windows listed at the dock in the bottom and when I had a chat waiting, the gmail title bar would change to "John says.." and flash discretely so that I always knew when I had a chat waiting while I was doing something else. With the new expose interface vs. the dock interface of seeing what windows are open, if you dont have sound on, how do you know when someone replied to your chat without you having to constantly check the window? Thanks!
