Chest Primer

A player opens a vanilla chest and presses the Primer button, or hovers over it and presses P. Items already inside the chest are then spread into the empty slots, and scrolling switches the filling between row and column order. Advanced sorting logic arranges the items so the slots end up balanced and sorted, which reduces the constant reorganizing that large storage setups tend to need.

Because the mod runs only on the client, it changes nothing on the server side. Players can use it on single-player worlds and on multiplayer servers without the server owner installing anything, and the work happens locally on the player's own machine. Fabric API is required and must be installed alongside it. The mod is published for Fabric only, for the game versions 26.1.2 – 26.2, and the code is covered by All rights reserved, so it is not open source.
