When you create an object it is picked, so you can go on in and meander making things, and talking about them without having to pick them.
It works well when you need to create a lot of new objects at one time, like in tile games, or bullet hells, or even particle like fx.
Yes I agree that we could use something more to deal with objects that aren't picked by conditions. We do have indexing, but its still limited, as it can only work on certain aspects.
Perhaps something similar to containers with an index, but without the disadvantages of only existing with the other objects.
Like the family trick with indexing maybe. In that primis I think that it would be better served if such a thing had no conditions like a family, just references in actions.
