Being able to reorder the attributes on a transformer is awesome. However, it's also tedious. Repeated right-clicks and selecting "Move Up" or "Move Down" in a long attribute list is painful.
It would be great if you could drag/drop attributes to change the order. So instead of clicking and dragging anywhere on the transformer to move it on the canvas, clicking and dragging an attribute should allow it to be moved up or down the list. Then transformers would only be moved on the canvas if you clicked the top of the transformer (where the name is displayed) and dragged it around.
