Gliider

This dead simple, outta-NY browser app features a toolbox that allows you to create trip profiles, drag & drop info from any website you want into the appropriate folder (flights, hotels, transport, food...), and quickly summon deal alerts from TravelZoo and Hotels.com. You can also share trips with up to 4 friends, or connect through Facebook to get travel tips from the ultimate resource: people you'd never actually want to see.
