From time to time I have messages in my inbox that, for whatever reason, I choose to leave in my inbox rather than archive them. As new messages appear, of course, the older messages move down the list. If someone mentions me in a comment, there is no notification that I have a new message. Therefore, I miss the message which is important. It would be helpful if there was a notification made and the message moved back to the top each time I am mentioned. Our team members have experienced the same problem. Having to go look to see if you have a new message doesn't seem logical.
