I'm using the Directions widget without displaying the directions on the screen. Afaik there's no switch to disable directions on the Directions widget, so I'm hiding them via CSS. I guess that it's a pretty common use case to just use the Directions widget as a good UI for route calculation.
Another use case I have requires to draw the route manually from the JS code, so I need to hide the route that is drawn by the Directions widget. Of course it would only be a performance win, if I could switch off route drawing in the first place.
I'm suggesting flags to turn off route drawing and directions display on the Directions widget.
