Seth,
Awesome tool! Probably my favorite tool in this miles/points world.
I just want to give a couple gui suggestions:
1. I like to look at the list of hotels on the right to see which ones have great values. But I can't figure out easily their location on the map without going through each balloon. And on a busy map (like Tokyo) this is not easy to do. It would be great if I can click / hover on a hotel link on the right and the corresponding balloon marker gets highlighted.
2. For the hotel chain list on the left, it would be great if you have a "Clear All" button. I often want to just look at hotels from one particular chain. Right now, I have to make 8 clicks to clear all other chains.
Thanks for making this tool.
