I have for long been thinking of an option for users to switch between dark/light background color. Both on thumbs-page and in lightbox.
You know that kind of button/symbol with sun/moon

-either during lightbox viewing or on the page with thumbs.
The most common way to do this is -what ever kind of light/white background I make as standard, the user is able to switch to black background.
I use Story mostly and would love to see that option there

Could something like that be done?
