One thing I'm finding as my user count increases is, it's hard to see who has been shared to what libraries. I know I can go user by user to select the shares, but it would also be nice to see who has each library shared from within the library view.
If I want to add someone to a specific library, they should already exist within my users group. If I want to restrict content from a specific rating/classification within the library I should be able to set this from within the library on a user by user basis.
In this way, if I find someone streaming something I don't think they should have access to, I can go into the library and verify their permissions for said content. If I modify that permissions during playback it should drop the stream completely and force a new selection on the user's part.
There are a lot of other things I would like to see regarding users and the whole interface we have for them. This is a good start to fix parts of the shortcomings, though.
