At the moment, you can only move objects up or down. It would be great if you could drag + drop objects into a different place in the list. It would also be good to be able to group similar objects in the list and sort by type.
At the moment, you would have to move spaceshiplargeenemy up many place (imagine a list with 100+ objects!), but if it could be type = spaceship, then you can sort by type, it would be grouped along with all the other spaceships. It would also be quicker if just one object is in an unusual place, to drag and drop it into place.
