yeah... it really would be nice if tracks disappeared a little quicker. i mean, right now "old tracks" often have no utility. the only use is determining where migration paths might be, otherwise they are very cluttering. it's very distracting to have ancient tracks all over your settlement, from animals that disappeared or were killed months ago. especially since they obscure new tracks, and it doesn't even really make sense that you would be able to determine which direction an animal traveled months prior, with many rains and such inbetween. it would be nice even if it were possible to erase old tracks using a spruce branch or some such.
