Drill
Needs a mod slot opposite from the collection port, mainly for an attaching worklight.
Mineral Extractor
Needs to have a larger sediment capacity, denser elements should not take hours to coordinate raw material at the base. The production should still only be 8 at a time though.
Base Building
I feel that the new platform system is nice, but would benefit greatly if they only allowed for 45° angle adjustment instead of 1°. This would make bases much cleaner. If nothing else add it to the settings menu, as an option for snapping base platforms.
