• When viewing a document that overflows the screen height, the next page action should: move the view port one screen down if it hasn't reach to bottom of the page, otherwise go to the next page and move the view port at the top of it (the previous page action should do the opposite: move the view port up or go to the previous page and move the view port to its bottom).
• Provide a way to crop the default margins of PDF documents.
• When viewing a detail of a large image, it might be worth having touch gesture (2-fingers tap?) to move the view port by one screen in one of the four possible directions.
• The page headers and footers should be optional.
• The EPUB margins should always be customizable.
• It seems that the document orientation is guessed from the first page : this is a problem when a document has heterogeneous page aspect ratios.
• When opening a text file: assume UTF-8 by default.
• There should be a rotate counterclockwise icon next to the existing rotate clockwise icon.
