# 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.
## Features
- **Controls**
- Press **G** to toggle preview
- Hold **H** for a momentary preview
_(Both keys are fully configurable in the controls menu.)_
- **Block filtering**
- Use **J** to switch between previewing:
- All blocks
- Only directional blocks (stairs, pistons, observers, etc.)
## Showcase
**TRANSPARENT mode**

**OUTLINE mode**

**CONFIGS**

## Dependencies (For versions >= 2.1.0)
### Fabric Dependencies
