HotbarLock

HotbarLock is a lightweight, fully client-side Fabric mod that lets you lock individual hotbar slots to prevent accidental item movement.

Features

• Lock any hotbar slot (1–9) — locked slots cannot be clicked, swapped, or modified from the inventory
• Offhand swap protection — pressing your swap-to-offhand key on a locked slot does nothing
• In-game overlay GUI — a small draggable window in your inventory screen with checkboxes for each slot
• Hideable UI — the window is hidden by default, press 0 to toggle it (rebindable inside the window)
• Persistent config — your locked slots and hotkey are saved between sessions, worlds, and servers
• 100% client-side — no server-side installation required, works on any server

How to Use

1. Open your inventory
2. Press 0 to show the HotbarLock window
3. Check the slots you want to lock
4. That's it — those slots are now protected

Dependencies

• Fabric API
