Hhotbar Keeper
by FlyingCoq
Hhotbar Keeper is a Fabric client mod that keeps chosen hotbar slots stocked from the main inventory.
What it does
A player pins whatever item sits in a hotbar slot, and when the stack in that slot drops below its maximum, the mod tops it up from the main inventory. The author wrote it after running out of blocks in the middle of a build. Each pinned slot receives a colored outline on the HUD, with the color chosen at random per pin, and the slot must be configured before it takes effect. Fabric API is required, the mod works on Minecraft 1.21.11 with Java 21, and it is client-side only, so servers do not need it. The author warns against using it on servers with anticheat.
