Google Maps Drag and Drop: Where Have You Been All My Life?

Here's an online-mapping feature I've been wanting for sometime: Google Maps' new drag-and-drop capability. If you don't like the route the program spits out for you, you can drag part of the route to a new spot, and Maps will automatically adjust your route to include that point and change the directions accordingly. Not only is this feature cool, but it is also extremely helpful for situations like these:

• You'd like to drive along the coast to make your trip more scenic.
• You want to avoid an area because you know the traffic will be bad there.
• You'd like to stop somewhere in particular on the way.
  
• You need to avoid a highway or road area because you are riding your bike. (This scenario is the most important to me.)

Neat, eh?
