Export selection as new world
A way to select multiple objects in your world, bring up the 'multi-selection' property panel (i.e. NOT a group), and click a new button to 'export selection as new world'. The new world would be named "<original world name> (Selection)" or something, similar to world cloning.
This feature would effectively solve the space junk problem, as people could just extract their wanted assets into a new world, leaving the space junk behind. They could carefully count the objects selected to be sure they are only getting the number they expect.
This feature would also greatly enhance the ability for people to share assets, as you could have a giant asset mall world, and people could go in and pick the one or two assets they actually want and export them into a new world w/o all the other stuff.

This is very important!!!
I started playing for a month. Create some swords and gave them out for free. Only to recently realize another editor of mine have been bringing in space junks into that world.
Now I felt bad for spreading space junks if someone imported my swords during that couple weeks.
Maybe also why my world wasnt very popular.
