For those of you using the "Follow A Game" feature, you now get the option of seeing the game as a miniature board on the home page. On the home page you'll see a link above the table containing all of the games you're following which says "Show games as a Diagram" where 'Diagram' is a link. Click on it and viola, little miniature boards. Click the link again and you get the table back.
The preference isn't saved when the page is reloaded, it always reverts to a table.
