The iBench gives you a portable crafting table with more options than the standard table. So not only will you be able to craft on the go, you can also store recipes for future use. That gives you an extra 9 available slots in your inventory if you should need it.
You’ll need to keep the bench in your main hot bar to access it. Then you can right click anywhere while holding it and the GUI will show up. You’ll now have some new options that make crafting a little nicer.
Making multiple items out of a full stack can be a bit of a hassle since you have to make the stacks even in order to make a bunch at once. Rather than placing all of the blocks in complete stacks, you can hit the Balance button or the ‘W’ key to balance all the stacks to even numbers. Just a bit of a time saver over evenly stacking items one by one.
You can also rotate what’s in the inventory for quick crafting changes. Let’s say you need to make a wooden door, some stairs and a trapdoor. Craft the stairs, take what you need then hit ‘a’ or ‘d’ to spin the recipe or the spin button. This will cycle through the door and the trapdoor recipes. It doesn’t work for everything but it is a cool feature to streamline your crafting a bit.
