That was very interesting - lately came back and made some flights in FBW A320, and knowing this would have come in handy in some occasions.
One little hint that I recently learned myself: when checking your flight plan in MCDU on the Navigation Display, it's much easier if you open the Navigation Display in a separate window by clicking on it with ALTGR+LeftClick - that way you can place the two displays side-by-side and easily scroll through the MCDU flight plan without messing with zoom and views.
