Lock & Order
by Makinuko
Lock & Order lets players freeze chosen inventory slots so that shift-clicks, hoppers, dispensers and sorting leave them alone, keeping valuable items safe.
What it does
Players can lock individual slots in the player inventory, the hotbar and portable containers such as shulker boxes and backpacks. Locked slots resist accidental dropping and automated sorting, and the system keeps the lock state saved between sessions. Hopper logic prioritizes refilling locked slots that already contain the same item, while locked hotbar and inventory slots can still be refilled from stacks in the rest of the inventory.
The mod is built for players who want firm control over their inventory without adding clutter to the interface. It stays close to vanilla behavior and adds no extra screens for the core function. Lock & Order is client and server, so the server and every player need it. Files cover Minecraft 1.20.1, 1.21 and 1.21.1 for Fabric, with 4.0.1-1.21.1 for 1.21.1 as the latest file.

Key features
Locked slots
Any slot in the inventory or hotbar can be frozen, so its item is not dropped or moved by sorting.
Protected dispensers and droppers
Dispensers and droppers do not fire or drop items from protected slots, so machines respect the locks set on containers.
Hopper filters and refill priority
Hoppers can be set to act as precise sorting systems, and they refill locked slots holding the same item first.
Quick move respects locks
Shift-click logic skips protected slots, which blocks unintended moves of locked items.
Backpack and storage support
Locks apply to portable containers, with added integration for Traveler's Backpack, Camping Backpacked, Simple Backpacks, Sophisticated Backpacks, and IronChests.
