A usable iPhone app sooner would be great - I support b).
But I do hope, Kris, you get some rest in between!

There are some minor wishes for the iPad version, although it's very close to perfect for me:
The sharing feature is great, I haven't seen that anywhere else. But when you think of emailing a book, it would be good to know the file size. Maybe ist's not hard to show the size in the metadata?

And I would love to be able to adjust the top margin, too. With the icons active, it just looks too crowded for my liking. There should be some whitespace, I think, but that's a matter of personal taste, of course.
(I do love the design of the icons, by the way).

Individual shelves would have been my greatest wish - I was pleased to learn that they are already on the roadmap.

Thanks again!
And I would feel honoured to take part in the iPhone app testing - please consider that.
