When I'm at work I like to keep my browser open so that when I get mail that an opponent has moved I can continue with the game. However, unless the player you last played has just moved, you have to refresh the page and only then can you click on the 'x games waiting' link.
Would it not perhaps be better to have a list of your opponents in a table on the far right of the page where the actual game is played? You could then get to that game with one click, instead of using refresh first. This would save time, and bandwidth for RHP.
Just an idea,
