I don't think the backgrounds idea is going to happen. I also don't like it.

It seems you are still trying to center the page number with the new mockup. That won't happen. The F icon will be hidden if you disab;e translations and recitations which is the default for a fresh install. The number will not be centered.

What's wrong with the T icon in the settings page ? It's still translations. I can add a menu and an entry to it for managing translations.

I thought about using icons for the various options in the index page:
1) The book for jump to page
2) End of aya-like icon for jumping to an aya
3) an icon I don't know about yet for jumping to part

This might make the options a bit more obvious.

I'm still going to work on the sura header but it will still obey the font size. I don't want to hardcode the size for it.

I'll also do the navigation soon. I'm not yet done with theming
