Multiworld support

I want to see Multiworld support in Sponge how it did in Bukkit. How they did it was nice and I liked it. I want to see simple support for players to hook into this for multiworld support. Like how it is in Bukkit. A simple idea.
If this is already available or it will be created sorry. Tell me nicely in the comments.

Sponge already has built-in support for multi-worlds.

Use a plugin like Project Worlds to manage custom worlds


I know about Project Worlds. I didn’t know about Sponge having Multiworld support itself. Thanks for the quick answer.
