Running 1.65 and came upon an interesting circumstance. On the Carbonite map when I enter an instance, there is a tiny little map of the instance that shows up in the upper left corner. It is quite small and difficult to see. Is there a way to swap the little instance map with the regular carbonite map?

Right click a non icon area of map. Select "Minimap...". Check "Full Size". There is also a "Toggle Full Size Minimap" key binding. Just set a key.

There is also the map option "Minimap toggles full size on entering or leaving an instance" that you could turn on.
