I'll be the first (and hopefully not the last) to say ^ and thanks for proactively soliciting feedback on the 'poweruser' side of farecompare. As someone who has sent in a number of suggestions over the past year (only to see much of the site move in the opposite direction), I welcome the opportunity to help improve this (understandably) minor portion of the site.
I'll hold off on concrete suggestions until I can come with up with concise, thought out list, but I hope everyone takes you up on the offer.
