Mini map needs z-axis

First off, I really like mini map that was introduced on 14 Sept.  There are several topics about it but one specific suggestion I wanted to share is to support a Z-axis for the view.  As an example, the map doesn’t work so well around the Volcano because you see the intersection of roadways that really don’t intersect at all.  It would be nice to have roadways that are, for example, over 50m higher or lower than your current position not shown.  Otherwise, I think it is quite nice.
