Pls add a World Feature where you can change the size of the world.

I think Minecraft should have a new World Size Slider that lets players choose how big their world is. The slider could range from 1 block all the way up to 30,000,000 blocks, which is the full size of a Java world.

This would be a great feature for a sandbox game like Minecraft because players could create tiny challenge worlds, medium custom maps, or full‑size survival worlds depending on what they want.

I think Mojang should add this feature to Java Edition first, and then bring it to Bedrock Edition later for parity.
