Make the fraction colouring more transparent, or have an option for it,
Shrink the grid labels on the small scale (zoomed out) maps as they are the same size as an outpost and obscures them,
Making the Grid Label's change size on different zoom levels will potentially slow down how responsive the map is when you zoom in/out, but we will look into it.
We are planning on allowing the user to control the opacity of the faction colors.
