Add an External User Only view to the Sharing / Roles section
We need the ability to quickly see and manage our internal users separately from our external users. We believe that a second view to separate the groups would be very helpful. We also believe that being able to select role and view all users in that role would be helpful as well. Finally, being able to sort the list by selecting an attribute and resorting the data (as we can in most all other views) would also be very helpful.
