ChestFill+
With ChestFill+, holding Shift over a chest, barrel or shulker box shows a preview of its contents in a clean grid, without opening it.
What it does
ChestFill+ is a client-side quality-of-life mod for Fabric. It shows a quick fill bar on any chest, barrel or shulker box, so a player can see how full the container is at a glance. Holding Shift while hovering over a container displays a visual preview of the items inside, laid out like a real inventory. This helps with sorting, exploring storage and building, since a player can judge which containers are worth opening and which are empty.
The preview is visual only. It does not give any advantage, does not change loot and does not alter what a container holds. Because the mod works entirely on the client side, it needs no installation on the server. Only the client needs it, and Fabric API is required alongside it. The mod is released under All rights reserved and is not open source. Files exist for 16 release versions, 1.21.1 – 26.3, with 1.1.0+mc26.3 as the latest Fabric file, published on 2026-10-14.
Key features
Fill bar on containers

Shift-hover item preview
Holding Shift while hovering over a container shows a clean, organized grid of the items inside.
Visual only
The preview changes nothing about the container or its loot, so it stays purely a display aid.
