Description
Blocks Previewer
Preview blocks before placing!

Ever placed a stair or piston the wrong way and had to break it again? Blocks Previewer lets you see how a block will be oriented before it’s placed, saving your time and frustration, especially useful for builders and redstoners.
This is a purely client-sided mod, and does not interact the server. Works similarly to Create’s placement preview, but for any block in Minecraft.
To open config for the mod, use the command /blockspreviewer or by using Mod Menu for Fabric or the built in (neo)Forge config menu.
