Blocks

I know that this won't come out in a while as we are getting the cave update but here are some ideas you could consider. Different types of TNT that have different types of radius. Being able to get heads for any thing you kill (with enchantments). Locked chest so you need a key or code. Torches glow without needing to place them (If in HUD) and can go in your offhand. Natural disasters such as volcanoes, Meteors etc. Making a conduit that lets you fly.

Thank You
