Allow flipping *everything* using the F & G keys.

Not just blueprints, but actual placed entities. Refineries, chemical plants, assemblers, belts, inserters, you name it.

Yes this would allow building properly mirrored chemical plant/oil refinery runs, freed from the curse of chirality. I consider that a plus.

Yeah, that would be very ideal. Though I guess oil / chem is supposed to be finnicky. It didn't occur to me this was going to be a problem and I always wondered why didn't do flip early on. Now I know!
