One problem that is beginning to be more serious as I play into deeper games is that I can't tell which faction is controlling what area.  Part of this is that I'm not familiar with the color schemes associated with the various factions yet, but part of the problem is that I am red-green colorblind and many of the colors used for the borders of influence are in the range that it is very hard for me to tell apart.  So it would be really really useful if there were some way for me to check who controls a particular area without having to interpret the colored lines.
