The interpreter view feature has a lot of useful features.
Notice how the bubbles are slightly transparent? That is to help the agency find overlaps which can happen when the agency assigns an interpreter to an appointment. The agency will know they are causing an overlap when they assign an interpreter with a (B), (V), or (O) next to their name.
By default an interpreter cannot claim an appointment that would cause an overlap. Clicking an interpreters name shows you just their appointments for that given day.
