I think it would be really nice to be able to turn the recipe auto-balancing on and off in the config, or to have seperate config options for the recipe amounts and the output.
As a side note - I really love the graphics for this mod! I spent so long looking for an advanced solar/accumulator mod that didn't just recolour or resize the base graphics, these additions look very fitting and feel like a natrual extension of vanilla factorio :)
