BHNS gallery example currently depends on PunctureTracker and VolumeIntegralGRMHD. Rahime and I wrote BHNSTracker to better track the stars. It has been tested for low resolution and it is now being tested for high resolution simulations. Once confirmed, it will be ready for a review for inclusion for the next release.
