Simon, I have to post this whilst I remember it's a cool feature I think to have.
Sometimes, if I'm AFK and someone says my name or any other notice the icon flashes @ sys tray, that is cool, however if 30-60 minutes or so has passed by since the notification and alot of chat is going on you have to 'trawl' back through the entire chat log to see where the notification was. Would it be possible to have the line HIGHLIGHTED where the notification was made?
Maybe the line can have a 'backcolour' so you can insta-scrollup to where any notification is made, or maybe the entire line be in BOLD or a user selected colour + bold?
Just a thought.
