that's really cool, but the font contrast is killer (bad) on certain parts in firefox nightly. I signed up; I can never seem to get as consistent with chess play as I'd like. I'd be thrilled if this helped me achieve those goals.
example : http://i.imgur.com/cqNPcgf.png . The light blue is really difficult to focus on using a laptop panel. I found myself cocking my head to see it more clearly. It may be more the font than the color. I don't know. The more I look at it the more it's the grey that bothers me rather than the blue. I can't put my finger on it, but something hurts readability for me.
