What Carbonite does is make another "minimap" for the user. Then they give you (the user) the option to
merge their "minimap" and Blizzards
default minimap. This gives you (the user) the "active node" gold icon, and the other icons, on the Carbonite minimized map (or minimap), which you would otherwise not get because there is no API to show it on other maps.
So there is another frame over the Blizzard minimap
if you choose to merge the maps. It's just Carbonites minimized map.
If someone could come up with a way to add
Click Menu to the right-click menu of the Carbonite minimized map, or add another menu to the right-click on Carbonites minimized map, that would be great.
