This style is a mod of the 4chan~ style by Mokocchi (http://freestyler.ws/style/99079/4chan-firefox-chrome). Most of what's been done is changing the color scheme and undoing a bunch of annoying changes.

On the index, threads have been outlined with a light shadow to show where each thread is. Before, it was basically impossible to tell where one thread ended and the other began. It was awful, and tbqh my solution isn't great either.

Board titles are no longer hidden.

Name, Subject, and Captcha input fields no longer have their text hidden unless your mouse is hovering over them. This was particularly annoying for the captcha field, since if you tabbed into it instead of clicking on it, you wouldn't be able to see what you were typing.

Threads are now wider, they take up more horizontal space.

File thumbnails were moved back to the left side of the post.

Unhid post numbers from the list of replies.

Quoted text now actually shows up as green. So do usernames and thread titles and crap.

Shadows all tweaked to be a bit more consistent. There's still some weird crap going on with the Quick Reply box that I haven't figured out yet, though.

I can't figure out how 4chan~ disabled a few features, I'm combing through the supplied json file to figure that out. Until I put up my own json file that's totally fixed of all the 4chan~ crap, just use the one supplied by Mokocchi.

For now you still need Open Sans, I'll probably replace that with a different font later.
