Adapting Copies

If You Copy A World, You Can Choose An Option Titled "Share Data With Original"

So, If Your Working On A Really Cool Project, Like Making A City, You Can Copy The World And Choose The Option, And Whenever You Do Something, It Happens On The World Copy. So If You Accidentally Delete The World Instead Of Downloading It You won't Lose Your Progress And Almost Break Your Laptop (I Say That From Personal Experience) Because It'll Be In The Copies, And On The Copied World, You Can Turn It On And Off If You Want To Add Something That won't Be In The Copied World!
