Stacking+
Salutations fellow Humans, I have made another Add-on. This brings non-stackable Items and 16 stack items to a stack size of 64! Exciting am I right? The Items are listed below in the description with an image.
Big Update!
Items that can stack to 64: All types of Potions, All types of Splash Potions, All types of Lingering Potions, All types of enchanted booksEnder Pearls, Eggs, Campfires(Idk how but they 3d and animated but I’m not complaining), All types of boats, Snowballs, All types of Signs, Honey Bottles, All types of horse armor, Saddles, All types of banners even custom ones as well!
update 1 and prob the final one lol: Potions, Splash Potions, Lingering Potions, and Enchanted Books are now stackable! I forgot crimson and warped signs and plus the stews! so I added them, enjoy!
WARNING: 
Please don’t do this because it will use all of the books and u won’t be able to get them back. So just put 1 not a whole stack okay byeeeee
Update 2:
All types of minecarts, all types of shulker boxes, and all types of music discs stack to 64 now!
Note:
If you have a shulker boxes that has the same items inside it will stack.

Note: Totems, Beds, armor, and tool wont stack so please don’t comment those down below.
