I think the way it will work is that a group will be able to contain either objects or other groups that are children of the group.

Then I think there will be a special group called "All objects" which is always available and lets you browse through all the objects underneath it, or use the group tools (hide /show / etc..) to apply to all objects that way.

Something like this:



But I am not working on that part quite yet though.
