Visualize coverage area

[MJS]

It's often difficult when you have a set of stations in a city to see what areas they cover - whether they overlap, whether anything is left out. It would be very useful to have some kind of colour shading for each station. (With different colours for each station in a city?) I attach a screenshot of a city where I'm completely lost as to what I'm covering - especially because bus and truck stops are so hard to find.

I like the idea. Like in Simutrans, you have the "V" button to do this.

Would be very handy.
