1. The titles of books are not in italics. Yes this is picky but when an entry is truncated an unfamiliar, the visual cue that it is a title is very helpful,
2. The option title "fit" indicates to me "fit entries to the screen" rather than select era. While the select predefined era feature is very nice, we also really need a "fit" ... Several times I've had trouble finding all the entries as given by the count at the top.
