Hello ! I've been searching for hours how I could zoom when I read a pdf or any image based book. I feel stupid because I don't see any answer on that on the web, so I guess everyone has found the way ^^; Still, this reader is clearly awesome, but considering I read a lot of pdf depicting tiny things ( like knitting schemes ), it would help a lot if I could find a way to zoom.
Thanks in advance !
