On menus, it is hard to see which main tab ("Team" "Players", "Arena"

is selected. It is hard to see the charcoal on gray and black, and besides I'm searching for the text rather than the underlying graphics.
So when, the top tab is selected, change the text color to match that of the secondary tabs, so I see them as being linked. And then change the text of the selected secondary color to a different color, instead of back to white. Or maybe highlight the secondary tab in some way.
