It would be fine if there is a per-channel (in particular I'm thinking of the moderator channel) option to get notifications (colored tab, blinking application like when your own name occurs) when something was written.
If I'm not mistaken, the channel's name is highlighted if there is something new (this includes battles, and mutes/bans). This does not hold true if you're outside of the application.
Thats right, the tab / channel name turns green then - but to observe this, you have to open the window and look at all tabs. I wish that in addition the application is blinking on new message for specified channels (eg. Moderators channel).
Actually, channel flashing could be a good idea, for those of us that end up with five or six channels open, we know what it's like when you get flashed and thenspend five minutes scrambling through to look where you were mentioned. Good idea, I think.
