Duplicating a group - (right now it just puts it as a sub group when you do) First you make a group from 3 items
When you select the "entire group"
When duplicating The following happens:  



The items are not in a new Group.
I can understand that when you copy items inside a group.
That you want them to stay inside.
But would be good if you select entire group specifically.
That it copies it in its entirety.  

Or am i missing something?

If not.  

Is there a quicker way then instead of having to remove them first.
Then adding to a separate new one?
Gets very tedious after a while :P
After using Shift+D to duplicate the group it will indeed create those ugly copies. No, go to Objects > Group > Remove From All Groups. Then just regroup them.

All the objects of interest should've stayed selected.
