Heyho, thank you for this one, I still craving for a loader mod with a 1x1 footprint. I've just have a little problem. Could you make it possible, that the loader will need the corresponding ingredients for their respective tiers?
Like for the highest tier (purple), it would be nitinol parts. An example for this would be Loader Redux for Bob's Logistics (https://mods.factorio.com/mod/LoaderRedux-BobLogistics).
I you could make this happen, I would really be pleased.
