Thanks for your interest. I just try to give you more info.
In the cutout of the “Off Route Situation” I inserted in pink as a place holder “Arrow is pointing to”.
This place holder can be replaced by A) Type or B) Name of the point the route indicator is pointing to.
With Type I mean the words of the selected item in the Dialog “Route indicator”.
In the screenshot of your preview for selecting Route indicator “Nearest point” is selected. Then in “Off Route Situation” the place holder would be replaced by “Nearest point”.
With Name I mean as noted by you “Via point X”, “Destination”, etc should be replacing the place holder.
At the moment I’m not a friend of the Name solution, because at rerouting the via points change their numbers. The Name solution perhaps is a good solution when user defined names for via points are possible.
The Type solution the user gives info of a setting of which he is not aware in the “Off Route” moment. Why the user is not aware of this? Using seldom the app, changing setting some times. And so this info is helpful.
I hope that I could help you and would be pleased to have the “Arrow is pointing to” info in a future Version of the app.
