Add a Bulldozer vehicle for smoothening tiny bumps or divots (but only in Dirt and Sand)
Often the ground isn't perfectly smooth, but instead has very tiny upwards bumps or downwards holes, and it just seems to me like total absolute crazy overkill to have to build a Mind Control Tower and assign an excavator and one or more Pick-Ups or Trucks, just to fix very, very minor absences of smoothness.
Instead, I'd like to be able to build and send a Bulldozer that has the seemingly magical ability to make very small amounts of Dirt or Sand appear or disappear as needed. I assign it to "smoothen" a particular area, and it trundles off and does that, then when it's done it returns to my Shipyard and goes into idle mode, until I assign it another task.
It's perfectly fine and realistic to have to muck about with Mind Control Towers, Excavators and truckage for larger height difference projects, but not for these tiny absences of ground smoothness, and it's actually not super unrealistic if it's strictly limited to work on only Dirt and Sand, while being very convenient.
