As an admin, I can see the list of members and what level of access they have (Viewer, Editor, etc) but I have no direct, easy way to identify ‘what’ each user has access to.
I would really value the option from the User Admin interface to see a user who for example has “Can view 1 file” and know exactly which file that user has visibility on. Much the same way as clicking on a user’s permissions which states “can edit 1 file” - that way if I need to edit permissions I know what access someone has.
