Stack Refill for Minecraft 1.21.9

During intense building or combat, it’s important that nothing breaks your focus. Stack Refill makes the process as smooth as possible: when the items in your hand run out, the game automatically replenishes them from your inventory. This applies to blocks, food, potions, tools, and weapons. You no longer need to manually open the menu to find replacements — the system does it for you.

It’s especially useful for builders placing hundreds of blocks in a row or fighters who can’t afford to pause mid-battle. While there might be a slight visual delay, functionally everything works perfectly. The mod adds convenience and continuity, making gameplay natural and free of annoying interruptions.

How to install the modification:

First step: download and install Fabric и Fabric API.

Second step: download the mod file.

Third step: copy Stack Refill mod package to the .minecraft/mods folder (if it does not exist, install Forge again or create it yourself).
