Explaining
Copper hasn't worked much since version 1.17 when it was added to the game. They can be used in the manufacture of lightning rods. It can be used in making binoculars by combining with amethyst. At 1.20 at the last moment they decided to craft the brushes with copper. And armor trims... Even with the copper golem added, it wouldn't do much. So many new functions can be added to copper. Instead of just adding a feature from update to update, an update with a side focus on copper may be good.
