From the gear icon you can now select a new sepia mode that I made this morning.

It doesn't save across pages yet for tests, but you can try it out by going into the gear icon in the sidebar and selecting sepia. To cancel it, just refresh the page.

Feel free to try it out across pages and let me know what you think of it or if we missed anything. It's still subject to change, under testing period, etc. but I think it's almost there.

Attached picture is sepia as part of a mockup for a "reading mode" without distractions. This is not implemented yet but will be the next step.

update: sepia mode now saves across pages and works perfectly well. There is a bit of a flash when you load a page with it on for a second as it loads the theme, which we will probably move to PHP eventually so that doesn't happen anymore. But you can use it, it's out in v1.
