Video History - Add "VIEWED" to videos in history that have been viewed by owners/users

After having to go through a week of video history to try to locate an event that happened, it would be nice if, after the video event in the history has been accessed/viewed by anyone, that it would then say "viewed", so you know which ones you or anyone that has access to them) have looked at and which ones you have not looked at, without having to delete anything. Maybe the little runner guy on the video history event could change color or something after it's been viewed. It would also let me know if someone else on my account has already looked at it, so I don't have to bother. Thanks!
