Shore port crane for Cargo Ships. Hover the crane and press R to toggle mode: loading or unloading. Requires straight-waterway directly in front (3x3) and within 2 tiles of shore.
Just did some tweaks on my own copy of the mod and it works as intended.
I added "tall = true," in the return of make_visuals() in protoypes/entity.lua.
I recommend only adding it to the visuals like this, and not the entity itself as the inserter is already invisible and should remain interactable :)
