TL;DR
I would like to increase the visibility of ghosts, so that I can see what should be placed (and of course: its alignment).can't see the ghost build underneath the grass. Requesting help.
As you can (not) see, there are some transport belts placed as ghosts. This never occurred as a problem to me too often in my past, but causes some disturbances now, as blueprints are available from start. I am sure other players are affected, too:now many players will place blueprints before a construction robot infrastructure of any kind is researched. When happened to spawn in a desert biome with grass, this will cause some serious problems placing items over grass, as shown in the screenshot.
