As a subscriber, I've been using QRZ quite a lot to further my grid chasing on 6 meters and satellite, and something I think would be quite useful would be better filtering options for searching on QRZ. For example, say I look up every ham in FN64. Currently, due to only being able to do one type of search at a time, it is very tedious to check through each listing to fine someone who may have even any info at all on QRZ, let alone helping find someone to sked. It would be very useful to narrow it down to, say, any ham who has actually put information on QRZ, versus a generic page or non-member listing. Or, you could use it to search for hams in said grid square, or DXCC, or whatever, with certain things in their biography - such as if they use certain bands, satellite, EME, or even certain modes or gear.
