I think they are a great improvement, but I would like to see, in future, the option to disable them and use only the GPS and charts. Just for a challenge. Maybe even some where you have none of that, only recommended directions.
There was one mission like this in FSX, you were in a microlight in the Sahara and you had to find this missing baby elephant. There were no waypoints, except to begin with to get you to the search area and you had the option to switch that off.
