Hello,
What you describe sounds reasonable. In terms of recording the mouse position, I’d say all one needs to do is start tracking the mouse before the participant starts dragging the element, and stop after they dropped it. Once implemented, the drag-and-drop element would log the event times for drag-start and drag-end (=drop), and one could use those to focus on the range of mouse coordinates in the relevant time window.
I’ll see about implementing such an element in the future release
