New to Navigator, I am experimenting to learn all of its features, of course!
Now, I tapped the map screen, to reveal the right-hand sidebar menu and touched the 'Start' icon. I do not know how to remove it or does it get superseded at some point?
Tapping the map and then touching the "Start" icon creates the starting route point. It gets superseded the next time you create a different Start point or you can go to settings-route-info and delete this or all routing points.
