That would be fantastic.
Have a scrollable list of your saved markers on the side of the map.
You could then click on one to make it active and when you exit the map, there's a subtle indicator that shows you what direction that active marker is.
That way if you have a goal of a trader or a particular resource, you always know which way to go.
Maybe have that ability as a craftable item that you wear.

Edit: Sorry quantum, didn't see your post, only the response.
