Map Updating

I would love to have the ability to auto-mark on the map while running around (probably with a module) so that different things you've encountered are findable again. Caves, exotics deposits, deep veins, etc. would be the first of many things that would be awesome to have on the map with its own icon. This would also be useful for showing where you've been during your current game. If it's added, it'd be a good add if you pass within a certain amount of meters to put it to the map with a marker.
