Add Blueprint/Ghost Building System for Easier Building in Survival Mode

I think Minecraft could really benefit from a blueprint/ghost structure system, similar to what games like The Forest or Valheim use. Players would be able to place a transparent version of a build in the world to preview and plan it, then build over it using real materials. This would be especially useful in survival mode — helping avoid block misplacement and wasted resources, while still keeping Minecraft’s hands-on, block-by-block feel. You’d use a Blueprint Table or Book to choose from preset builds (like houses or towers), or save and reuse your own. A ghost version appears where you want it, and you build over it block by block, turning it into the real structure. Optional features: Save your own builds as blueprints. Find or trade rare blueprints from villagers or chests. Get a list of required materials. Support for multiplayer blueprint building. This idea would make building easier and more creative, especially for new or survival players. It wouldn’t change the open-ended nature of Minecraft — just give players the option to plan better and build more confidently.
