Inv Tweaker
by ThisBusch
Inv Tweaker is a Fabric inventory sorting mod that tries to bring back the behavior of the older Inventory Tweaks mod, with sorting and hotbar refilling bound to keys.
What it does
Inv Tweaker sorts the player inventory and chests with a key press. Its sorting modes are alphabetical, compact, row grouping and column grouping, and a key cycles between them. Unlike sorters that only order items alphabetically, it can group items horizontally or vertically, which keeps chests from looking cluttered and makes it easier to find item types again.
The mod also refills the hotbar automatically. When a stack in a hotbar slot is used up, the next matching stack moves in from the inventory, so building or eating can continue without opening the inventory. Auto refill can be switched on and off with a key. The sorting works in singleplayer and multiplayer, and the author notes support for other mods such as Reinforced Chests.
Inv Tweaker is a client-side only mod, so only the player needs it and servers run without it. It requires Fabric API and is published for Fabric only, across game versions 1.21.6, 1.21.7 and 1.21.8. The latest file, 0.6.15, targets 1.21.8. The mod is released under All rights reserved, so it is not open source, and its files may not be altered or redistributed without permission.

Adjustable key bindings
Sorting and refill actions are bound to keys that can be rebound to fit the player's controls.
