I use an addon called
Mapster to help the Blizzard maps act a little better when I want to see them. It works with Carbonite if you have the maps merged. I can see the
Gatherer node icons on the Carbonite minimized map. I also use
Archy bugfix (a "fan update" of Archy untill the author has time to work on it himself) for my archaeology skill and Carbonites minimized map will show me the area for the dig site I am working. I don't see anything on the Carbonite maximized map because I have the Blizzard minimap set to hide when I maximize the Carbonite map.
In flight:
Working the site:
It works for me, anyway.
