Change color of track - mid way

It would be super helpful to be able to

               - change the color of the track mid-way

                  (ie.  hiking along, start the return, and change the color at that point).  

                  It seems like it would be an easy thing to incorporate into the program

                - and, it would also be useful to be able to do split stats (time, mileage, elevation gain)

                   on hikes

Thanks, Anne
