I use Digital Editions for reading technical manuals. Quite often, the text refers to diagram which is on the oposite page e.g. the text on page 316 references a diagram on page 317 that can only be viewed when "turning the page" in Digital Editions.
Wouldn't it be great if there was a view similar to "Fit Double Pages" that only turned over one page at a time? e.g. you have page 315 and 316 open,you press page down and you now have page 316 and 317 open. This would allow you to continue reading the text on page 316 and easily reference the diagram on page 317.
