There are a few comic-centered readers out there already that are similar, like Comic Rocket

Are there any requirements that need to be met for adding a site? For example, when I added my site to the Piperka listing, there were specific HTML standards
that were requested for the sake of having the crawler work correctly.
You may want to put a label or something on the bottom bar, or change the alt text on the display button to "Show randomizer bar." It wasn't hard to figure out what it was, but I had no idea what it did before and immediately after clicking.
