Alerts for Potentially Inaccurate FR24 Paths

When a FR24 path is imported, there are times when there is no known location between two reported points, and the router just takes this to mean the plane flew in a straight line between these points. I think it would be useful, for points further than some distance (maybe 50km), for the user to be alerted that the actual route taken between two specific points is unknown. This is hard for the user to know without a notice because planes often do fly on straight paths, so the difference between the imported path having an accurate straight line or a potentially inaccurate straight line is not really possible to distinguish. I recently had an issue with this and only realized there was a large error in an imported path when comparing it to a picture I took on the plane. It would be good to know on import so I can more easily catch these mistakes in the future.
