Hi there I've had a look at the existing PDF readers, I've tried Repligo which amazingly doesn't seem to allow full screen, and also seems a little - blurry? At least it remembers what page I'm at. The Adobe reader seems to render oddly when I zoom in - doesn't remember where I am in huge files when I close the program, and is generally really short on options. I'm used to Goodreader on the iphone - that had cropping, you could lock your zoom level so you could freely scroll around without having to readjust for columns - it was just really good. Is there anything like that?
