Having noted a few comments about the PNF not knowing what the PF is doing with the side-stick, it is worth noting that in the Ground Mode after start-up the side-stick position is shown on each PFD.
My suggestion is that in Flight Mode that this option is selectable, and when in other than Normal Law and on auto A/P disconnect, that the side-stick summed position be shown automatically on both displays. Both pilots and the 3rd or 4th seat occupants will also see what is happening.
