Have been playing with it for a while. I find the type faces too small with too much unused space on the page. Equipment should be listed on the initial listing of flight choices rather than having to pick the flight and then going to the seat map. For the multiple destination option, one should be able to specify the cabin for each leg (e.g. business overnight versus economy in the daytime return). A nice feature as you drill down is seeing the difference in basic fares -- business versus econ -- for your particular choice -- and being able to make a change.
