Displaying Rare monster on the mini-map

When we destroy n monsters, all Rare monsters are displayed on the map.
But I propose to make a display of those who are in close proximity to us (very often monsters remain around the corner, due to darkness in the location or passages blocked by jugs/chests).
Add a Rare monster icon to the mini-map when it is within a certain radius of the player.

+1.. or just make the rare already visible in the starting of the map.. the map is so huge that walking take so long.. then u turn around cuz a rare is inside a small enclosure that was not open. stupid how they forget to not check it..

I think the problem is not that we destroy N monsters, its that you have to kill until there are just 200 left. It would be better if it were just kill X instead of killing all but 200.
