Suggestion for new upgrades

I would really like to see a couple more things that resemble the original Minecraft game, such as an offhand (left hand that you can hold something with, without really using it), a shield to go in the offhand, a wolf (or different species of the wolf-fox category) that you can tame with bones and heal with raw meat, a horse you can ride, or the ability to build golems. As I already said, I would really like to see some of these things, and they would make the game so much more fun (in my humble opinion). Thanks for taking the time to read this (I know I probably typed too long of a message) and I hope to see some of these upgrades in the future.
