This is really just because I added this mod mid-save and was rather annoyed to find that my most basic Assemblers now required Syngas/Synthetic Plates with no option to disable the change.

The issue is, while I'd like to add more options to the Settings menu, because I usually like to tweak things myself, I also don't want to clog the Settings menu with dozens upon dozens of options, overwhelming most players. Maybe there's a way to expand the Settings conditionally. I will investigate what can be done.

Thanks for the suggestion anyway, I'm glad to see that more options are wanted ;)

I have expanded the Mod Settings. You can now remove Synthetic plates from the Assembler recipe … or crank it up to 255, your choice!
Just install Full Control to make the settings visible.

Again, thanks for the suggestion.
