Option to Rotate Blocks
This would be a helpful feature, especially for stairs. It's very annoying to have stairs only able to point in one direction. It could be under the Z-Axis menu under build tools, where you can select directions north, south, east, and west.
Yeah, or you can use something like r to rotate it. Would be very useful for doors, as when you open them, it open left/right, an it looks weird to walk through a door.
