It would be really nice if the developers could find a way of adding missed approach. This could be dotted line, or a line in a different colour that one selects, maybe by adding the waypoints manually.
Also, it would be good to have a vertical attitude line. You guys might have seen this in boeings and Airbuses. On the ND this line tells you where your selected climb or descend at current f/p will end. Always helpful when needing to clear altitude constraints.
