Hotbar Config
by HotdogError
Hotbar Config lets players save custom hotbar layouts and assign specific items to fixed slots, opened from an in-game menu on the H key.
What it does
Once an item is assigned to a slot, it returns there whenever it is picked up, provided that slot exists in the hotbar. Assigned slots are kept free of other items, so a reserved slot stays intact even during busy play. The layout a player defines is the layout the inventory keeps, without rearranging by hand.
Several presets can be stored and switched between depending on the activity, such as construction, travel or fighting. Any preset can be changed at any time, which gives a player full control over the inventory layout. The mod is built for simple use while still offering organization features that cut down the time spent managing the inventory.
Installation requires Fabric. The mod runs on the client only, so servers do not need it and players can join without installing it. Files are published for 1.21.11 only, with version 1.0.0 as the latest Fabric file, released on 2026-03-22 under the MIT License. The mod is not open source.

In-game preset menu

Reserved slot handling
