Revert arrow binding when moving single arrow

Revert arrow binding when moving single arrow: As of now, there is no way to rebind an arrow other than dragging the point handle, which is frustrating as one needs to manually adjust every single point. It's especially annoying with slight adjustments, which lead to slightly different arrow length / angle, so it needs to be additionally manually repositioned. Instead, rebinding the arrow should be as simple as dragging it, as we've had it before.
