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)
