When I work in planner mode and select the 'waypoints' option in the left-hand column, a rather wide column appears on the right, containing a great deal of information that I don't immediately need. This takes up a significant amount of space, which limits the view of the map.
In my opinion, the layout used in the older version of the MRA route planner is better: the waypoints are listed in a sidebar on the left, and when you click on a waypoint, a small box appears on the map. If you then want more details about that waypoint, you can access them via additional buttons.
