I was wondering if I re-design my store, including deleting the current collections and menus etc, would I then at a later date be able to go back to the previous layout/design including the original menus and collections if needed, or would I need to re do everything.
Any help is much appreciated,

Thanks for your good question.
yes you can do you just back up your like theme and downloads also you have work copy theme so doesn't effect on you current store
