I would like to propose the suggestion that thralls and pets that are follow your be allowed have their own marker upon death for quicker location of the their body . Given the glitchy nature of disappearing bodies and rubber flinging of corpses this would go a long way in helping locating their final resting places.
Also, it would be nice if the dead follower could be seen on the map if switch on in the follow list for a time and beside their name in the list would be dead again to aid in locating their corpse.
If you go to your followers page you can track selected followers which gives them a map marker, I use it to find them if I die when they are following
It would be really nice to also have a dead thrall marker
