I've made a quick mock-up to show what I mean. With the game speed options, now they're a list of radio buttons. Just one click to select instead of two, and easier to notice what's selected. I think the Dominion card set selection should also use the same style.
I've changed the "(no presentation yet)" message area to a dropdown list of recently used messages which could be edited like away messages in IM programs. Different custom messages should be saved for each game on BGA, and it would be helpful if the message used in the previous game was automatically selected for the next game.
Also, a "•" is placed between each player's name in the "Around this table now" area. This helps keep them separate and distinct, especially with 2-part names (like Albumine Tagada).
