Feature Requests: Editing Points in an Existing Run

I sometimes run most of a previously mapped run, but then add an extra loop or turn to it, increasing the distance. I would like to be able to  add checkpoints to the mapped run stored in the system instead of having to start all over for each variant of an existing run. I appreciate being able to move existing checkpoints, but I'd like to also be able to insert and delete checkpoints as well.

You should be able to do it. If you go to edit your existing route, then click on the point you want to add a point near, the little box should pop up. The tab to the right says "Add/Delete" and you can choose to add a point before or after that one. Most of the time it works ok, but I find (and this may be user error) that sometimes when i go to edit an existing route, its gets royally screwed up somehow where the points get disconnected and I can't get it back together. Good luck!
