Can we get a Location Pointer on the map to show the area we are looking at in the Elevation Profile Pane (Left Sidebar, 84.63 ft). In the photo you will see a Black Arrow pointing to the location that is currently being shown in the Elevation Profile Pane. As you move in the Elevation Pane the Black Arrow moves along the line to represent that location.
Also allow the sliding of the Black Arrow and have it show the location in the Elevation Profile Pane.
The Black Arrow can be anything like what I drew or a ball on the line, it might be touch select the Grey or White Dots that allows to move the Distance Line.
