Mapnificent
If we could find a browser Mapnificient worked in without problems we'd probably call it the greatest thing to happen to Google Maps since turn-by-turn navigation. Even with it's painfully slow performance (Firefox) and tendency to crash (Chrome), we're still in love. Basically, it lets you filter and search maps based on travel time using public transportation. Its great for finding apartments with the shortest commute or a fair meeting place that you and a friend can reach at the same time. It's pretty impressive and, if its creator Stefan Wehrmeyer ever whips up a mobile app, it could become an indispensable part of our smartphone arsenal.
