Maybe this should just be an option as opposed to "the norm," but it would be really, really, REALLY great if directions could automatically turn themselves off once you've gotten to where you wanted to go.
It irks me that I (a) have to use the mouse to close the directions dialog [keyboard only girl here, as much as possible], and (b) that I get told to go back where I came from (or that I'm off the path) once I leave my destination.
Food for thought! Directions are a fantastic option, though. :) Thank you so much for implementing them.
