The raid chat highlight experiment is great, but the highlight doesn't need to stick around the entire stream. Limiting the duration of the highlight, either by time (say, 15 minutes) or by messages (say, first 5 messages after the raid) would make this highlight far more usable; as-is, I'm tempted to disable it, since my regulars are getting all their messages highlighted because they came in with a raid at the start of stream.
