title is my number 1 suggestion, verticality is efficiency!
next would be ‘road lock’ so that specific sections can’t be deleted accidentally!
next requires some splainin but each node on a road has a max number of 4 roads and in order to place a road section above/below a node with less than 4 roads, you currently have to fill the nodes with roads. Thus, a way of filling the nodes with something that acted as though there were a road (dead end? direction of travel signs?) but not, would be good!
another idea is power lines above roads, an addition to road nodes?
Thanks for reading!
