I know I can right click and select "copy visualization".
However, given the way the rest of the interface works Ctrl + Dragging a component seems to be the most intuitive way to make a copy
It would be nice if this was made available 🙂
Agree wholeheartedly here on this suggestion - in fact, we even considered it initially. There was some difficulty in getting the layout correct with the dragging, since you are copying instead of moving the visualization. Not impossible, but just more difficult than we originally expected. We still want to do this.
