Builder Mode for Minecraft Java and Bedrock

I think Minecraft should have a dedicated Builder Mode available for both Java Edition and Bedrock Edition.

Many builders use third-party tools such as WorldEdit to create large projects, but Bedrock players often have fewer options and many players on consoles cannot use mods at all. A Builder Mode would give all players access to powerful building tools in vanilla Minecraft.

Features could include:

• Built-in WorldEdit-style tools for selecting, copying, pasting, rotating, and mirroring builds.

• Easy-to-use menus instead of complicated command syntax.

• Undo and redo options for large projects.

• Shape generators for spheres, circles, cylinders, and other structures.

• Symmetry and measurement tools.

• Ready-to-use command-related blocks for things like teleporters, timers, checkpoints, scoreboards, NPC dialogue, and adventure maps.

• Visual interfaces for command blocks to make them easier to learn.

• Advanced building tools that work the same on Java and Bedrock so all players have access to the same creative possibilities.

Builder Mode could be optional when creating a world so Creative Mode stays simple for players who do not need advanced tools.

This would make building, map making, and creating adventure worlds much easier, especially for Bedrock players on consoles and mobile devices who cannot easily access third-party building tools.
