What if assemblers only assembled? This is an overhaul mod that introduces interesting production chains and design choices. New ores, new concepts, new assemblers, new intermediates -- and new challenges to overcome.
So, I have not yet figured out a way to do this yet. That said, I think it's a good QoL thing, especially considering the extended burner phase, so I'll be looking into it. :)
There's already a mod that does this called burner leach (or something along those lines). I feel like it could just be made into an optional dependency.
