I was thinking, maybe we can have reverse tracking or whatever it could be called.
For example, with the current tracking we see:
A small deer was here in the last couple of days and went south-west.
Maybe with expert or tracking mastery, we could also see where they came from.
A small deer came here from the north-east in the last couple of days and went south-west.
An outsider came here from the north-east quite a while ago and went north-east.
An elephant came here from the south a long time ago and went west.
Not sure how difficult to code that would be though. What do you guys think?
