This idea has been developed and deployed to Canvas
For observers of multiple students, it can be confusing to determine which notification belongs to which observed student. It would be helpful if notifications (email, text, or mobile) delivered to observers of multiple students had some sort of identity associated to them. This could be name, initials, or username.
Because not all observers follow multiple students, perhaps this could be an option for observers to select as they connect their Canvas account to their student(s)'s.
This functionality would take the guess-work out of actively following students and improve the Canvas experience for anyone who is an observer -- parent, coach, guidance, advisor, etc., especially from the web.
