HotbarLoader
Save and load hotbars in Survival with customizable keybind combos (e.g. H + J to save, K + J to load). Missing items are simply skipped.
About this Mod
HotbarLoader lets you quickly save your current hotbar and restore it later—no menus, no commands.
Features
- Two fully configurable keybinds: Save Hotbar and Load Hotbar (change them in Minecraft’s Controls menu)
- Pick a hotbar preset by pressing a second key: e.g. H + 1 or H + J to save, K + 1 or K + J to load
- When loading, only uses items that actually exist in your inventory (missing items are skipped)
- If the same item appears multiple times, it prefers the largest available stacks and tries to consolidate them into a full stack when possible
- Client-side storage (per installation), no server mod required
How to use
- Save: hold your save key and press a second key (e.g. H + 1 / H + J)
- Load: hold your load key and press the same second key (e.g. K + 1 / K + J)
- Note: Loading only works when no GUI is open and your cursor stack is empty.
Compatibility
- Fabric, client-only
- Minecraft 1.21.x (this project is currently set up for 1.21.11)
