Both good ideas, I will look into how we display country names in the scoreboard. I can't imagine it will be too hard, I have seen it before. Does everyone like that? Speak up if you don't.
As far as buttons, I don't think we can have one set of buttons for the pedia and one for the adviser screen. We'd have to use flags for everything. We'll see how it looks when the map is made and then we can make changes. Flag buttons are already used for every civ, so we have them handy.
Honestly, I suspect that screen is going to be pretty well worthless no matter what. I don't use it when I play a 34 civ game, to crowded. We have 46(47?) playable civs.
