i3 is an extremely well-designed and well-thought out inventory mod. Everything is almost perfect. However, it would be nice to have a Creative crafting guide; and there seems to be some sort of bug with the skins. When Edit Skin, for example, is enabled with i3, my reach in Creative will be about four metres, instead of ten. I still have not been able to find the exact code source of this bug, but it has been very annoying and I would love to see it fixed.
Otherwise 100% recommended! Thank you, jp, for many hours of wonderful time in Minetest with a brilliant inventory.
