Farm

When building a greenhouse farm, I found that the ground for construction requires soil. However, this means I need to level the entire rocky ground first and then re-lay soil. I suggest that building a greenhouse does not require a strictly soil-based ground. Instead, it should consume a certain amount of soil during construction and be built directly on any type of ground.

This is a good idea, it would be so much easier than manually removing the layer of surface rock and replacing it with dirt using a mine control tower. Just include the needed amount of dirt in the recipe, and bam!

Yep. This is a very tedious part of the game. And I rarely have a spare excavator lying around that can do this, let alone get it done quickly. Heck, I would even accept where you also are required to haul away rock in addition to delivering dirt for construction.
