The loader idea is cool and only changes some gimmicky gameplay. As it's working in the graphic it's a bit overpower though. I would make it 3x2 so you can't place them perfect inline with conveyor belts. This would make it a powerfull item to load/unload chests and trains, but it would make it less...

Nice Mod. I wanted to automate the construction of the Tier 6 Miner, but it won't work because both the the second and third assembly machines only take 1 stack of Processing Units (100), while 125 are needed for construction to begin. Is there a method to get their production automated?
