In the Appointments tab, agenda view, you can currently see the researcher's name, user name, time slot, and number of requests. It would be helpful for there to also be an indication of their clearance status (perhaps with a column for cleared/not cleared, or by using a different text color or background shading for the different statuses). That way, it would be easy to look at the day's researchers and get a feel for how many are new, versus returning. Perhaps clearance status can show up in all the available views if possible.
