KoHs Inventory Tweaks

Support update (September 2026): KoHs Inventory Tweaks now supports Minecraft 1.21.11 and later. The 1.21.10 builds stay downloadable as archived versions but no longer receive fixes or new features.

Your inventory, your rules

KoHs Inventory Tweaks is the client-side successor to KoHs Inv Cursor, maintained for Minecraft 1.21.11, 26.1, 26.1.1, 26.1.2, and 26.2. It gives you precise cursor placement, faster and more reliable inventory input, visual customization, item highlighting, and an inventory-only GUI scaler—all through a responsive purple configuration menu, with a little cat to keep you company.

The mod keeps normal Minecraft inventory rules. It does not require installation on the server and does not add automated item transfers or custom inventory packets.

New in 1.2.0

The slot that lights up is the slot you click. With the GUI Scaler on, 1.1.1 highlighted one slot while a click, F, 1-9 or Q went to its neighbour at 63 of 560 slot edges. 1.2.0 has none, on all five versions.
Center Mouse Fix in one move — the pointer is placed once, before your inventory opens, and nothing rewrites it afterwards.
Inventory Tweaks as a tree — Shortcuts follow the pointer now sits under Super Fast Inventory and rests while its parent is off. Pixel-perfect scale moved to the GUI Scaler page.
Animated icons made of real Minecraft items and particles, waking up under your pointer.
The Zymekoh mascot — a little cat made from the Zymekoh skin that lives in every window. Pet it, carry it, throw it, and feed it Totems of Undying from your inventory preview.
KoHs tab — meet Zymekoh, who makes every KoHs mod, with links to Discord, the KoHs Mod Suite site, Modrinth and Buy me a coffee. Bring the cat to her face and she gets cross.

Features

Cursor Landing — choose where the cursor appears in your inventory, single or double chests, Ender Chests, and barrels. Every container can be individually disabled to keep its Vanilla behavior.
Center Mouse Fix — places the cursor in a single move right as Minecraft releases the mouse, before your inventory exists. A hand already moving toward a totem or any item is never pulled back.
Super Fast Inventory — opens the local inventory up to one tick (50 ms) sooner, and waits only when Vanilla would still run something first, such as a pending attack or an item in use.
Shortcuts follow the pointer — under Super Fast Inventory: F, 1-9, Q and Ctrl+Q act on the slot under your pointer the moment you press them, even right after a fast flick, in your inventory and every Vanilla container.
Customization — recolor inventory and slot frames, control opacity and world backdrop darkness, or use a cropped image, GIF, or short video background.
Resource-pack aware — choose the active resource-pack inventory texture or the Vanilla base, then apply KoHs customization above it.
Item Highlighter — search Vanilla items and configure slot colors, borders, hotbar highlighting, and dynamic hover highlighting.
GUI Scaler — resize only the player inventory, including its slots, text, items, and character model. Pixel-perfect scale keeps every slot even and sharp.
Player Visibility — tint and a glowing silhouette for the players you can already see while your inventory is open. Blocks hide both: nothing shows through walls.
Zymekoh mascot — it breathes, blinks, follows your pointer and reacts to your switches. It only eats Totems of Undying, pulled by magic from your inventory preview: your real inventory is never touched. Five make it round and heavy for ten minutes. Turn it off on the Inventory Tweaks page or hide it from its menu.
The interface — dark violet glass, animated icons that no graphics or particle setting stills, controls that never shift under your pointer, hover explanations, and pages that fit at GUI scale 2, 3 and 4.
English and Spanish — every supported Spanish locale uses the Spanish interface; other languages fall back to English.
