Best Tools
Switches to the best tool you're carrying whenever you mine, so you don't end up breaking stone with a wooden pickaxe by mistake.
How It Works
With it on, each block you mine switches you to the best matching tool in your hotbar (or your whole inventory, if you've set it up that way). You don't have to scroll to the right pickaxe or axe yourself.
Commands
