Old habits die hard, that's for sure. But like I said above, I was also someone who did the more than 1 chat window, and started out that way in EQ2.
While I do find it annoying to have to scroll over (say you have too many chat tabs in one window), it'd still probably work better for the implementation as Rothgar stated.
Personally I wish custom sound triggers existed in-game, rather than through external log readers. I simply just don't like turn on logging unless I really wanna test out DPS.
Another thing that I hate, is you can only totally filter out so much through options. The rest is controlled through Chat Filters, and they have to go SOMEWHERE. If you uncheck it from a secondary tab/window... it goes back to Main chat..... annoying to me...
Ok getting off track
Hoping to mess with mock-ups here soon...
