I would LOVE to see a route line on the companion map. Something like the white line when you’re selecting a route that outlines the course, but once you start the ride, you have no idea where you’re headed. A stop/start would be great! Thanks 
I totally support this suggestion. I have been thinking this would be a great feature, especially for the longer routes. You can only memorize so much from the initial route map when starting your ride. Would be great to have it highlight the route you have chosen on the companion app, but maybe even have two different highlights, one for the portion of the route you have completed and a different highlight for where you are going. These could be automatically disabled as soon as you manually turn off of the planned route, although keeping a highlight/track of where you have been would still be interesting.
