"Insert point" at map right click should insert the point at mouse position, not inbetween the current two selected points

probably quite easy to do?

As far as I can see, it's not possible to move route points except to manually alter the lat/lon values which is quite cumbersome. Drag/drop would be awesome, but even by just adjusting the "Insert point" logic for map right click would solve it largely.
