All items are stackable by default to 64, they get updated once they're in your inventory

All items that are normally stackable up to 1 or 16 are now stackable up to 64

Config

/trigger bigger_stack_size.config

If disabled in the config, all items will reset when you split them up in your inventory

To choose what items are stackable

Edit this file:

datapack/bigger_stack_size/tags/item/stackable.json

To make certain items temporarily unstackable, e.g. for an item sorter:

Name the item "unstackable" with an anvil

To update items from a version below 1.21.6

/trigger bigger_stack_size.update_items

Updates every item in your inventory, make sure to not have items that have custom data you don't want to loose (e.g. from other datapacks)

How to Enable Cheats Permanently After World Creation

If you encounter this issue, here is a step by step guide on how to enable Cheats/Admincommands permanently after you have already created a Minecraft world.

⚠️ Before you begin, you should save and backup your world in case something goes wrong. (I will not take any responsibility for any corrupt worlds. Do this at your own risk!) But don't worry this works without any problems. If you don't want to change this permanently check out this guide.
