ahh, one more point.
would it be possible to keep the numbers/dar bars/dots etc a constant color instead of becoming dim during sunset, clouds, or sunrise? Even when zoomed in, it's really tough to read the characters during these times.
and, i think someone also mentioned a point about making the color of the map icons independent of the colors of player icons. this might be a less complicated implementation for readability of the map than the black boxes i have proposed above.
just some more thoughts.
