Liked the navigation and chapter name theme improvement... i'll be waiting for the translated Surah names.. btw the navigation bar opacity should be little bit more visible.. as its very light (because it will contrast the navigation buttons and make them more visible).. i have an idea for the search page merging into the index page. i.e use the magnify icon in index dockbar for search..

The translation button idea is really good, i was thinking for the one too.. also you can group similar functions under one head.. i.e translation font, translation manager (downloader and remover) under Translations. etc.
