Stacker
Minecraft mod to change the stack size of all items. For Fabric 1.17, 1.18, 1.18.2, and 1.19!

This mod has a config that defaults to 64. Change it to be whatever you like (below int_max), but I do not recommend anything too far over 1 Billion (No support will be given for stacks larger than 1,073,741,823).
Requires Stacc API and Cloth Config API. Stacc API is an embedded library, so don't worry about downloading it. I recommend installing with Mod Menu (for in-game access to the configs), but it is not needed to run.
All Versions
+ Add VersionAdded #stacker:not_stackable tag, for mod and modpack compatibility
Tweaked priority on AnvilScreenHandlerMixin, to be compatible with a few more mods (Charm will require a mixin plugin, for now you will have to manually disable their stackable enchanted books config)
Updated Simplified Chinese Translation (Thanks BradNotBad!)

Change config GUI to better fit smaller resolutions
Now, you can set the max stack size of tags and items, as well as a fallback max count
Also:
Fixed mod conflicts with TechReborn and Inmis
Fixed bundle crash (thanks to Devan-Kerman)
Properly mark Cloth Config API as a required dependency. Now Fabric API clearly states it is missing, instead of giving a harder to parse crash report.
