Train stops should show up on the map

Not sure if this should be a bug report, but train stops in 0.15 don't show up on the map if you disable the "train stop names" option. I think they should have a 2x2 blue pixel like other player-made entities.

Sometimes you don't want train stops to pollute the map at all.

Current system is okayish - maybe make a display train names switch have 3 values (none, stops, stops with names).

I'm not talking about the huge dot/circle. I'm talking about the train stop entity having no minimap color unlike every other entity.
