Hi,
here is a idea to make Plex more usefull for parents.
In the past I have created a seperatly user account for my children. The kids have only access to audiobooks, TV shows and movies for kids. Our 6 year old son use my iPad mini to view movies. Of course, only limited time, but sometimes he hides with the iPad in the children’s room to look secretly. This is not so cool. Sure, I talk with my Son very often about this situation, but sometimes it works and sometimes does not. But this is not the point 
I think a parental control, like “this user can only use Plex between 3 PM and 5 PM” or “this user can only use Plex 1 Hour a day”, would be a nice idea for other parents too.
Perhaps this can also be applied to a particular library. For example “movie library from 3 PM to 6PM” and “audiobook library always open to use” or similar.
What do you think?
