While placing some factories and entities, I noticed that the alignment lines were being obstructed by the building cost overlay. If that was not in the way, it was very clear where the lines were, both the alignment lines and the boundary lines. However, with the building construction costs on screen, all of that was hidden.
I would like an optional mappable command that makes that overlay not appear as a toggle. Press it again, the overlay comes back, press it again, it goes away.
