- Early 0il industry buildings (fluid pump, pumpjack, storage tank, refinery, chemical plant)
- Defense items (shotgun + shells, gun turret, flamethrower, basic ammo)
- T1 speed and productivity modules
- Red inserters (and maybe blue ones)
- Steel furnaces (as an alternative to skipping straight to Electric)
or better yet, a custom item field or externally editable config. If you feel up to it, of course. :>
