For xbox 360 version:

I suggest that there be a way to create a "special portal" that can link your world to another one of your created worlds.

I don't think it would make much of a difference except that the player would be able to move inventory items from one world to another.

This would create a way to keep old worlds (and your creations), while still being able to explore new structures or modifications to the terrain generator when updates take effect.

This is a feature that I feel would seperate the xbox version from the pc version and possibly open up new options for sharing worlds between other players if that is possible on a console.

This exact idea, almost word for word, has been suggested more times than I care to count.
