This is a data pack that makes every single item be stackable up to 99!
You can go mining, exploring or more with a much more organised inventory since slots now hold 30% more items and blocks!
This even works with items that can only be stacked to less than 64, like doors and swords.
I was going to make it so that all items went up to the 32-bit integer limit (2147483647), but Minecraft's vanilla mechanics only allow you to modify stack limit up to 99 :(
Note that only items that have been picked up/been in entity format can stack higher than 64! Getting items straight from the creative inventory or /give will make them have their old limits until dropped and picked up again!
Also note that if you don't have the strongest processor and have too many big items could cause lag! Regardless of your PC, I recommend allocating at least 4GB of RAM to Minecraft if possible (I would only advise you to do that if you have 8GB+ memory)
If you want to add some items that can't be stacked to 99 go to data/mega_stacks/tags/item/not_valid.json and edit the file.

Have something to say?
this is also ticking me off because it's not a proper integer.
I'm not sure, it could depending on how many items the people hold
If you do plan to install it maybe use a different server as a test just to make sure, you wouldn't want to lose the SMP
