If is possible I think it will be a useful feature to limit every invited friend or family member by time.
For example if I specify for “family member 1” account that he can view maximum 10 hours of movie in every month when he used the time he receives a message that “your movie watching limit exceeded.” but he able to see the movie list, the trailers etc… only can’t start or continue to watching the movies.
I invited some friend but many of them watching to much movies and I have a very big outgoing internet traffic. It will be nice to limit all of them that can use my plex for maximum X hours
First I think to limit by number of movies that he can watch / month but is not ok because in many cases they only start the movie seeking on them to see if is good or not and stop playing. So it is better option to limit for hours.
