I think there may be another thread on “adjusting route line colors” in order to not obscure road/street names and route numbers. If so, please point me to it! But I’ll start here, and ask if, instead of adjusting route line colors, it would be possible to put names/numbers on an overlay layer, above the route line. That is, layers:
Street/road names & route number plaques.
Of course this ordering/layering would be baked in and not a Map Layer adjustable by the user. I hope this is clear!
We do have a plan to move text into an overlay layer that would help with a number of issues including keeping horizontal text horizontal on rotation and fixing the occasional text cut offs. Unfortunately this is a huge task, we already spent about 2 man months of time on it and it is no where close to finished so we had to pause on this for the moment to implement higher priority stuff. Multi-device Favorites sync is scheduled for our next major update, and contour maps to follow.
