I installed iBouquiniste Lite (the free version). There doesn't seem to be a way to get ragged right instead of justified text. Is there in the for-pay version?

It's really remarkable how all of these ebook reader apps claim that their particular app will change the way you read. I suppose that's true if you're going from printed book to ebook reader, but going from ebook reader to ebook reader is a lot like going from one word processor to another -- some have features you love, and some have features that drive you nuts, but in the end, they're all pretty damned similar.
