I'm so far not a great fan of the adjustable line height. It's ok when it works, but in some books, it behaves very badly, (an example I have is a book where the Chapter headers line touch and overlap a bit, but the paragraph text has huge gaps between lines wasting over half the screen space.) Of course, I've always fixed books with bad line spacing directly, the abilit to adjust that with a slider is no doubt the best thing since sliced bread for people who can't. It just needs tuning for the corner cases where it goes kooky. I'm having trouble isolating the causes of malfunction, however.

Edit: In the light of a new day and slight lowered expectations, the 'problem', or inconsistency, is not nearly as bad as my earlier impression.
