It can be useful to use the Animal Tracker perk to hunt animals for meat, leather, and feathers, as (valid) animals will show up on your compass within a larger radius and directly on your screen in a smaller radius. However, once the animal is killed, the signal completely disappears, making it a bit difficult to track down the corpse for harvesting - especially if the animal is small and the grass is tall. I propose that the signal instead persists for a few seconds after the animal is killed, so the would-be hunter can more easily find their slain quarry.
