The orangestone, copperstone ou Bluestone.

With Redstone, we were able to do several things within the game, but something that would help is a new Redstone for the upright position. I know that with the new update of minecraft caves and cliffs we will have the Sculk Block, but an Bluestone (a Redstone joins with lapis-lazuli) or orangestone / copperstone (a Redstone joins with copper, because copper is also a mystery used for the production of electrically conductive materials, such as wires and cables), this would not only bring an evolution to Redstone, but also an additional function for copper or lapis-lazuli.
