Agree with your answer. That is definitely one-dimensional.
Did not explore QlikView much, but in QlikSense liked the flexibility of Data Manager to go back and try to change fields. Doing from Data load editor is more like programming perspective.
Anyways, in my opinion more flexibility to the user from Data Manager can add to more simplicity.
