I feel like it would be a great addition if there was a button to reset a place's drawn area and redraw it. In RI, we draw schools by the shape of the building and with many schools being demolished and completely rebuilt into a different shape, its very tedious and annoying to have to go around and either delete all the points or to go just move each one, one at a time. Same thing goes for parking lots.

It isn't a huge inconvenience, but it definitely would help a lot!
