I was thinking about a notification pop up or even an alert when someone has made an edit in a PM.
Since it's sometimes can be quite confusing when someone made an edit to a PM (especially when you're in the midst of replying) a notification stating "USER has made an edit to reply #XX this PM" or an alert when they made an edit would be welcomed.
