Pick Block Lock
by CoolAid
Pick Block Lock lets players reserve hotbar slots so that the pick block key chooses blocks from those slots first, for Fabric, NeoForge and Quilt.
What it does
Players mark specific hotbar slots as locked, and when the pick block key is used on a block, the mod prioritizes the locked slots when it looks for a matching item. Locked slots are managed from a hotbar screen opened with the B key by default, where a player assigns which slot holds which block. Choices are saved automatically through the mod's config file, so the arrangement persists between sessions.
When the hotbar is full, locked slots can be rotated through so a block is placed in a chosen position without emptying the bar first. The mod needs Fabric API and runs on the client and the server, so both sides carry it. Files are published for Fabric, NeoForge and Quilt, with the 1.21.11 build covering 1.21.11 – 26.2 across five release versions, and the code is open source under the MIT License.
Key features
Locked hotbar slots
Specific hotbar slots can be locked so that pick block selects from them before any other slot.
Slot assignment screen
A hotbar screen, opened with B by default, lets players assign blocks to each locked slot.
Automatic saving
Slot choices are written to the config file as they are made and loaded again on the next launch.
Rotation through locked slots
When the hotbar is full, the locked slots can be cycled through to choose where a picked block goes.

Use cases
Building with a fixed palette
A builder can keep frequently used blocks in locked slots so repeated picks land in the same places.
Who it’s for: Builders and survival players who pick blocks often and want the same blocks to stay in predictable hotbar positions. Server owners can run it as well, since it is installed on both sides.
How it compares

Pick Block Lock is different in that it runs on both client and server and covers the 1.21.11 – 26.2 range on three loaders.
