change to black text on white background in the organize, content update pages, etc. etc.
i hate working on the black backgrounds and white text. Really difficult to read, especially if your eyesight isn't perfect. Puts me off so much it's taken me two years to start really customizing my site.
It is very hard to see the options with the black background when organizing photos. Research has proven that older eyes have difficulty with colored backgrounds and white or near white works best. Consider your older subscribers, too.
