Dreamwidth style system discussion

Hrm--I think that style got made (with some changes) into a style called Practicality in the style browser. I can understand if it's not what you're looking for since it doesn't have the navigation on the top, but in modules on the side, but if it looks acceptable enough, you can use it, then apply the theme Warmth for Practicality (it's the direct descendent of the stylesheet you are using, I think). Then, go to the images section of the customize area:

And put the image URL in the "header background image" section.
