coppers for redstone and tools

Copper is used widely in real life, and in minecraft, only thing you can do with it is making a lightning rod.

So my opinion is to creating a electric wire.

Unlike redstone, wires can be vertically connected up to a maximun of 4 blocks, and you can also attach them to walls by using shift+right-click.

4 wires can be crafted using 1 redstone and 2 copper ingots.

If mojang doesn't like to add new items, lighting rod can have this feature.

Also, add copper tools.

Copper tool's efficiency is between stone and iron tools. 

Since copper is highly conductive, it takes more damage when struck by lightning.

Copper tools rust when the player is holding when inside the water.

Thank you for reading my opinion(if anyone did)
