I think it would be very useful, cool and Mac to use a coverflow view to the books of our library. This would put to use the multitouch functions that Macs now have. To flip through Book covers would be a great addition.
Along that same line maybe a preview using the space bar that gives a synopsis of a resource and a couple of pages we can use in a preview window without opening the full book. That's probably my least favorite.
These would help us to identify books and also preview new/unused resources.
As you know the Magic Mouse allows for multitouch as does the trackpad on all current model Mac portables. On my MacBook Pro I can use 3 finger swipe to move forward and back in documents, and webpages. I think using multouch to flip pages through our Bibles and commentaries would be very cool and intuitive Vs. just scrolling endlessly. It would also let it match better with the iPhone app.
