Actually, this info is (sort of) under My Games -> My Performance... and while it's all games - not just rated - and there are no percentages listed, they are broken down by Black, White, and All.

Edit: tried to quote a previous post stating that we need to have them broken down by color instead of W/L/D, but muffed it up.
I'm glad to see the overall win/draw/loss percentage breakdown is included in the stats. Thank you.
Now we would like to see that breakdown for games as White, and games as Black. I don't really see the point of knowing what percentage of my won games were with White or with Black (and similarly for losses and draws).
