Philipp Lenssen reports that Google Maps has added a very useful feature to Google Maps. You can now plot multiple destinations for your trip. For example, I plotted a trip from my office, to a 100 Broadway, NY, NY and then to 14 Avenue R, Brooklyn, NY. Small feature, but very useful feature, that almost all mapping products have already. To work this yourself, after you set a destination from point A to point B, click on the “add destination” link to add more points to the map.
