Lwib
by StarZebra
Lwib gives players clickable custom buttons in their inventory screen, and each button can send a command or chat message when pressed.
What it does
Lwib is a lightweight client-side inventory button mod. Buttons can be placed in the inventory screen and clicked to run a command or send a chat message. Button icons can be vanilla Minecraft items, and the background color can be changed or removed. Joining a world or server and running lwibedit starts the editing mode.
Buttons can be placed anywhere in the inventory, which can cause overlap with vanilla slots and other mods' interface elements. By default a Lwib button takes click priority over the slot beneath it, so that slot can become unusable for normal use until the button is moved. The layout is set in-game, and the gallery on the project page shows example screens.
The mod runs on Fabric for 1.21.10 and later, with builds covering 1.21.10, 26.1, 26.1.1, 26.1.2 and 26.2. Only the client needs it, so players can use it on any server without server-side installation. It is released under the GNU General Public License v3.0 or later, and the source code and issue tracker are public.
