Small footprint  really customizable [3-star edit: The backup functionality does NOT backup the appearance settings  a pitty. ] You can modify the style to anything you like  but it takes some playing around the settings to get something nice. This would definitely benefit from some pre-made styles and a quick way to change text size and margins (why are all margins separate? No clue). Either way  it's a great reader that will definitely stay in my phone since it barely takes any space at all :)
