Do you play SkyBlock or just use cobblestone generators a lot, but hate sitting there holding down the click, only to switch your pickaxe every 10 minutes when your old one breaks? Then you need AutoMiner! Brought to you by the maker of Minecraft Mod Mover and Minecraft Hot Keys. With AutoMiner, all you need to do is fill in your inventory and go to your cobblestone generator. AutoMiner does everything else! AutoMiner holds down the left click for you and changes the pickaxes when they break! It can even tell you ahead of time how long it will take and how many stacks of cobblestone you will have when you're done. It's that simple! When your last pickaxe breaks, AutoMiner will play a tone for you so you can go craft more pickaxes.
