Would it be possible to be able to control the opacity of the map?
Within the menu system, the player can determine how translucent or opaque to make the map.
In addition, there could be an option to make the map opaque when the player mouses over the area where the map usually is and then it can go back to the desired level of translucency when the mouse is removed.
This would make for a larger viewing area typically without needing the player to move the camera.
Just a suggestion.
