The seventh tool out of editor_mode. It reads the selected set of tracks and the tab shown through the services, digitizes the tracks it lays and refreshes the plan after it sets one parallel to another. The panel shown for two selected tracks is a public call of the tool, and the self-test command parallel moves with it and lays the same tracks as before.
