This UI works ok for portrait, but requires too many clicks around the screen for landscape use IMO * use.

For example, the title bar at the top takes too much space to do what is essentially a menu that should simply accept search queries as well as direct scripture references. In the application shot shown, the slider is probably a bit much.

The library at the bottom makes sense, but is too also taking up space where it doesn't need to. The bottom bar, since this is consistent in Maemo 5 should probably contextually change to showing icons/avatars of the resources contained versus being a second box on the top. With the left-most icon serving as a "back/cancel."

I'm a fan of the book/chapter/verse selection screen from my Bible+ days, and it makes sense from a stylus-use standpoint. If used, I'd recommend something of a mixed mode approach, where typing on either one of the book/chapter/verse screens narrows down the items presented - making it much easier to do finger/stylus navigation.

The last shot of the text looks about what I've thought as well. Nothing but the text, and anything additional to come from either tapping on the title bar (opens a search/go-to panel) or doing a gesture-based action within the reading area to bring up more advanced commands.
