Advanced typographical features, no matter what's in the book.
Fonts, ligatures, drop caps, perfect subscripts and superscripts. Justification of lines and even hyphenation if your system supports the language of the book you read.
It works out of the box. Even if the book you read was never prepared with typographical finesse in mind.
But if you want to customize it to suit your fancy, it's your call.
