Is it possible to have an "add point" mode similar to how you have the "select point" mode that would add a point where the mouse is clicked and places it between the 2 'closest' track points on the map? If this is unmanageable, then maybe you can select the points you want to add it between beforehand? When in "select point" or "add point" mode, it would be great if the right mouse button would work like the "pan map" mode so I could scroll the map as I'm adding/editing the map.
