button for "move selected marker under my feet" and then for the xyz position floating next to the selected marker, if z pos could change color (red/green) if the marker is below/above me. And also I think we talked about it already but just in case: "duplicate selected marker under my feet". Also, some toggleable highlights that will show all the points of the trail, so I can quickly identify parts where is abundant amount of them. And some another toggle, that will show disabled markers/trail in like 25% opacity, uneditable, unclickable.
