This one isn't so much a problem as it is a functionality extension, (read: request :x) but when managing groups, there is no way of telling what user falls into what category other than looking at the Manage User page. I think it might be nice if a list of users for each group was generated when editing group permissions, it could be pretty helpful.

Or, if that idea doesn't work, a way to sort the Manage User table by group (or any column for that matter) would be a nice addition, for when sites become larger than just a couple of users.
