Notification or icon that someone has left message on ticket

not sure if this is already available and I don’t know about it or if it’s something that can be added.  I would like to see in my ticket view some sort of icon or wording that lets me know someone has added a comment.  Right now it says updated and a time but that can change based on many factors.  would be nice to see that a user has left a comment so I can then go to that ticket.  thank you
