I thought a drill for your truck or rover would be a great addition for mining capabilities, as well as thrusters to reach further planets
i also think a great addition would be adding names to your bases and planets, as well as making a shelter, or living quarters with a bed to sleep to day or a central map that has to be researched as well with a bed and oxygen tanks,
I also think storage that can open and be placed inside as well as outside to make a more available and expansive storage for players
