In addition to being able to edit routes on the itinerary map, you can perform
some operations using the Features > Edit > Path menu option of the
itinerary page which cannot be easily accomplished on the map. E.g. Splitting
the route. Sometimes it can also be difficult to select and delete points on
the map when they are very close together, so navigating through the points in
the Edit path mode provides another method to identify and delete them.
Editing routes is very similar to editing tracks as described above.
