I like to watch my stats so that I can see how I'm progressing as a player. But my stats aren't really representative, as I lost dozens of games when I was just starting out and learning the game. It would be nice to be able to view stats for the *n* most recent games, for example.
There would be no end to the possible ways to summarize your past games, though, and I don't expect Fizzer to spend lots of time making that possible. I'm more than happy to do this myself, as I might be the only person odd enough to want to look at how I perform in 1 v 1 games on Mondays where the opponent went first and I had to choose a new color.
Just an XML dump of all the information displayed in the My Games tab would be amazing. Even the ability to select text in the My Games tab would be a fine start. (Alternatively, if there's a way to select text from a Flash application that I don't know about, please tell me.)
