I think the Passenger Lounge needs a filter dropdown like the Mission Board has in order to find or exclude certain types of requests. I think there are far too many Sightseeing Missions showing up and would like a means to filter for other passenger types quicker, just like you can filter for legal/transport/combat etc from the requests on the standard mission board. It's not a feature, just a minor tweak to help make finding suitable passengers easier and quicker.
