About Data Driven Stack Sizes

From Modrinth

Override default `max_stack_size`s using data-driven item tags (Data Not Included).Increase the maximum value of the max-stack-size data component for 99 to 2048. Dev on all my projects will be paused for the duration of the BDS boycott against Microsoft.

This mod changes the max_stack_size data component's behavior, allowing for stacks larger than 99 (upto 2048).

It also automatically changes how a stack's max_stack_size component behaves when it is checked, allowing for data-driven stack-sizes where changing how much an item stacks to is as simple as adding it to that value's .json file.

For a example of what the mod can do, see Data Driven Stacks Example Datapack
