All up I like what you're doing but it's broken in Opera. After playing in Firefox:

- Text selection is really awkward, drag too far and you select unrelated stuff from nearby elements instead or as well

- The navigation stuff feels really weird down the bottom, probably because most software puts that stuff up the top

- The blue/gray page strip is weird, it feels more like a zoom tool rather than page navigation

- In book/slideshow mode the length of the page and the toolbar being all the way at the bottom makes me think I should still be scrolling

- Zooming in book mode has some of the site components overlaying it, in slideshow mode it adjusts properly
