My main use case does not actually refer to waypoints, but to any points on the route.
For example, if I decide to take a previously unplanned break during navigation. Then it would be great to be able to click on any point on the route that has not yet been created as a shaping point or waypoint, and to display the distance and expected duration to this point.
Or, for example, click on a POI (petrol station, …) and get its distance and duration displayed.
So you can decide whether to take the next break there or look for another place on the route.
One possibility would of course be to add this point as a new waypoint and then display the distance and duration to this waypoint as discussed in App: Select next waypoint to display
But it would be optimal if it were not necessary to create a new waypoint, but rather to be able to find out this information for any point along the route without creating a waypoint.
