If you have a number of clients, it would be nice to be able to sort by first_name or last_name when looking for a client.
If I manually edit the url to: /admin/clients/index/active/?sort=last_name&order=asc the client list is sorted by last name, so it seems like this would be an "easy" change.
I am populating the company field with last_name, first_name; it would be better if we had two columns.
