Rails highlighted in conveyor overlay ?

[Binbinhfr]

Hi there,

in power overlay, electric wires are clearly highlighted.

in plumbing overlay, pipes are clearly highlighted

in ventilation overlay, gas pipes are clearly highlighted

in automation overlay, automation wires are clearly highlighted.

These features are very useful.

So, in conveyor overlay, why are rails not highlighted ?  It's really missing. We have no way to clearly see the global rail system, in order to organize it ?

Please implement this feature.

Thanks for this great game.

EDIT : oh infact, a friend of mine just told me that the rails are effectively colored differently in conveyor overvlay, but with a dark purple color, almost impossible to differenciate from the grey background... Could you make this purple color more shiny ? (like the colors in electric/pipe/automation view)
