Redstone Wires: Vertical Redstone

Crafting Recipe - 1 redstone dust surrounded by 4 copper nuggets.

Use - Similar to redstone dust, redstone wires are able to connect to other redstone wires, redstone dust, and other redstone components, but unlike redstone dust can be placed on the side or bottoms of blocks to make connecting redstone easier. As a drawback, redstone wires can only connect to 2 other redstone components, so to make t or + interesctions, redstone dust is required.

Why should this be added: Redstone wires would give redstone engineers more freedom when making redstone contraptions, allowing freer placement. They also give another use to copper which, while it has more uses than when it was first added, could still use more imo.
