This feature would be similar to the map notes feature. Except’ instead of covering a single tile, you’ll be able to mark a series of tiles with a custom line.
The intention of this is to allow players to mark paths through cities or dense environments that are difficult to drive through. This way, you’ll always know the best path to take through them when returning.
Now, would a feature like this be worth the effort, and moreover, possible for a newbie like me to implement?
