Possible ideas for a future update

This is just an idea but what if you made a copper shield same recipe as a normal shield but replace the iron with a copper ingot but the copper shield has less durability. Another idea to make copper more useful add tin so that you can make bronze and I feel like the recipe on the crafting table should be 1 tin in the middle and 8 copper surrounding it to make 9 bronze ingots and with bronze you can make bronze tools and amor for the tools same as iron but a little more durability and amor has just a tad more protection and a bronze shield too. For the tin ore I feel like it should be around as common as iron and to help balance it when you mine tin it drops raw tin nuggets.
