I have been wishing for a long time to have an outline feature in Google maps (or any map tool for that matter). I always want to compare the size of things (partly because of the distortion of the projection), say is the city of SF larger or smaller than NYC? I was stoked when Google added city boundaries, so that means they know them. Now there just needs to be a way to select a city, state/province/department/whatever, or country and drag it somewhere.
