Just a small nit, and it may even be theme specific, but on the notification bar at the top, there is one for messages, and one for the user name. The first is obviously for messages, while the other has more things that cause a notification highlight. But that includes messages. So if you read your messages, the message highlight goes away, but the notification over the user stays, even if that was caused only by the messages. So one has to open both the messages and the user notification to clear the notification highlight. Would be nice not to have to do that.
