About this Mod
Hotbar Helper
Hotbar Helper is a client-side mod that keeps your hotbar full and your tools ready. It automatically restocks empty slots and switches to the right tool when you mine, so you spend less time thinking and more time mining. Every feature is configurable to be enabled/disabled. All 1.21 versions are supported
Features
Automatic Hotbar Refill
All of the following methods of emptying a hotbar slot are automatically refilled:
- Block placement
- Eating
- Item drop
- Throwing
Refilling happens instantly so you can keep building, eating, or throwing without opening your inventory.
Auto Tool Switch
When you start mining a block, the mod selects the best tool in your hotbar. It considers:
- Tool type
- Tool durability (prevents you from breaking)
- Tool enchantments
When finished mining, it returns to your original slot. This means you can do things like build, break stone with a pick, and break dirt with a shovel all without hitting a single hotbar key!
