Information

Minecraft version: 1.21.4
Modloader: Forge

Mod name: Stack Refill

Feature description

We don't need to automatically refill slot, more than that we need all items stackable, e. g. 16 milk buckets, 16 water bottles, 16 stews of the same type. Even if we use your mod, we still need to fill 16 slots for 16 non-stackable items, so we don't have much place for other items in inventory.
Make such mod or give link to it if you already made it.
Thanks,

I don't, but there are definitely some out there. Thanks for the interest!
