There are now 10 different colours to chose from if the default blue isn't your thing. Just look at the bottom left of each page and you'll see a drop down selector where you can choose. Each colour comes in fixed width (1050px) and fluid width (fills your browser window).
Seriously, this is a major improvement. Took a bit of getting used to, but now I have found my way around it is so much better. Thanks for all the effort you put in to make it happen. Here's to the next 10 years.
