YES! THANK YOU. This is what I've always wanted in a flight search tool. Seriously... that link has lifted a stress off of my shoulders. I DREAD looking for plane tickets and having to deal with the horrible interfaces on the travel sites that force you to go through back clicks and start overs to expand search options. This site is brilliant. Thank you thank you thank you.

[edit]Okay, I got a bit two excited to quick, and overall it's still by far the best I've seen, but it's missing two important features.

1. Multi-leg flights.
2. the ability to time shift the departure and arrival days as easily as you can all of the other features you can toggle and weed out. A simple +1 or -1 days link would rule.
