it may be tpo useful and might be too broken but realistically backpacks exist irl and so should too in ccnet, apparently when I dig up the ccnet resourcepack, most of the sf items are in there including the disabled ones like backpacks, now what zaify can do to make this work is to only enable the smallest form of backpack and make it 3 slots, make it so that u can only carry 1 in your inventory, make it so that there should only be 1 in chests, can't place backpacks in hoppers, minecart hoppers, barrels, echest, and all of the nook and cranny u can place items in, including dispensers, it adds a slice of life in game by adding space and adds a bit of that tasty realism. But it doesn't really matter whether it's added or not
