Super simple quality-of-life mod. This mod adds the ability to place an entity down by left clicking a ghost. You must be in range to place. It bypasses having to pull the item onto your cursor stack via the pipette tool and avoids having to manually ensure that the item aligns in the appropriate orientation-- the mod uses the existing entity-ghost orientation.
