The highlight for unselected chat channels receiving text is a nice start. But I think it would make more sense to highlight channels with text that hasn't shown up in other channels yet. Or make that a selectable option.
I've got both FC and LS chat in my main "General" tab. I also have them by themselves on a separate tab, so I can read just those without shouts, progress messages, etc. cluttering them up. This tab is constantly highlighted now.
Or make an option to just disable the highlighting completely for each individual tab.
