Upgrade StoragePrivate/Public Group Options
It'd be nice if we could have another option in which a group was viewable by those who were not logged in/in the group, but was not listed on the "Groups" section. Alternatively, offering a system in which a group admin could create a password to distribute so that people could view the group without being in the group would be another useful feature, since adding multiple lists of students to a single group every semester would probably get tiring; just issuing a single pass code could get by much of that and allows me to (mostly) control who has access to the library.
