I think the interface is pretty good and has gotten better the last few releases. If you'd like my opinion, I'd change the navigation a bit in the Bible view. A forward/back that works like a browser would be a great feature, being able to very quickly go to the previous verse/chapter you were viewing and being able to quickly go back without losing your train of thought by looking for the right buttons, etc, would be great. The reference history dropdown is a good start, but not quite as easy as a web-browser-like history forward/back.
There are three sets of forward/back arrows in the toolbar, I've used it regularly and still always forget which is which and have to hover to see the tooltip. I think simplifying it by adding a bar at the bottom just for navigation would make it far more user friendly. It would allow more room than just the little icons to show what each button actually does and being at the bottom it would be where your eyes and mouse cursor would naturally be when you finish a chapter.
I'm attaching a crude mockup.
