This is a quick and simple but very useful tool for replenishing health in a timely manner in Minecraft. It adds two slots to the left of your screen that can be filled with any food. Simply highlight the food you want over there and hit shift+G for the top slot or shift+H for the bottom slot. And the food will instantly move.
Then just go about your travels. You now have two freed slots in your inventory that can be used for other tools or materials instead of food stuffs. When you need to eat just hit G or H and you’ll start eating the food, no need for holding down keys or waiting to replenish your health.
