Pre-Placement Block Rotation
by jcwd
Pre-Placement Block Rotation lets a player turn a block to the chosen orientation before it is placed, on Fabric 1.21 – 1.21.8.
What it does
Vanilla Minecraft often locks a directional block into a fixed orientation depending on where the player is looking, which makes straight-up and straight-down placements or awkward angles hard to get right. This client-side mod removes those restrictions, so a block can be rotated or flipped with the controls before it is placed, and a translucent preview shows the final orientation in real time.
The mod works with most directional blocks, such as observers facing north, and aims to make building faster, for example when stacking dirt towers, replacing blocks or placing scaffolding that needs several passes. Controls are set under Minecraft Options, Controls, Rotation Placement, and the mod can be switched off instantly whenever it is not needed. It requires Fabric Loader, and its environment is client and server, though the current release is limited to singleplayer; multiplayer support still needs block placement synchronization work.

What the author says
The current release is Singleplayer Only. We are actively working on making the system compatible with Multiplayer servers, but due to how Minecraft handles block placement and synchronization, additional work is required.
