What we're missing is the ability to group shared calendars to allow a quick view of a group of calendars. Our call center schedules appointments for students with student services associates. They need to be able to quickly view the calendars for groups of associates according to their specialty. If there are three Computer Science associates they need to see all three of their calendars at once to find an available appointment and then quickly select a different group on the next call.
There's a grouping function discussed in
this thread that could form the basis for what we need. Aside from the lack of a client interface it also doesn't do quite what we need. It should enable and disable all of the child folders when you select or deselect the parent folder.
