More Offhand Slots
by AkkynaA
More Offhand Slots lets players hold up to nine items in the offhand and cycle between them with keybinds or the scroll wheel.
What it does
The mod expands the single vanilla offhand slot into a row of extra slots. Players switch between held items with keybinds, Mouse Button 4 and 5, or the scroll wheel, and the cycling can be bound to a modifier key, limited to offhand items only, or made to skip empty slots. A HUD indicator shows the previous and next items with their counts, and its position can be moved with X and Y offsets.
Settings are stored in moreoffhandslots-client.toml and can also be changed through an in-game config screen that uses YACL. The mod bundles SlotLib, which adds a button to the inventory screen that opens an extra slot inventory for managing offhand items directly. Files are published for Forge and NeoForge, with the environment set to client and server and the license set to the GNU Lesser General Public License v3.0 or later, so the source is open.
