TomTom group member arrow will hijack TomTom to point and show distance to your fellow players in same party or raid as you. Make sure you have Tomtom installed too.
/ttta stick will stick to your current target.
/ttta unstick will clear the sticky target and track the current target again.
It uses HereBeDragons to acquire player positions and do distance calculations.
This is a continuation of the abandoned plugin TomTomTargetArrow.
