At the moment the waypoint/via-point option on my GUI only has room for the current available waypoint (in this case Shenley Brook End, which the user can select) and another waypoint the user can suggest.
In a case where there were additional waypoints to select (e.g. not only Shenley Brook End but Westcroft, Oxley Park - lets presume that up to 7 additional waypoints can be available... making it 8 in total... not all at once but over a period of time), how could this interface change to accomodate this?
