I was in the middle of a book, right at the good part, when I updated my phone and ipad. When I tried to open stanza and continue my book, it flipped out, froze both devices, and tried to hijack my home screen. I liked being able to change the background, text size and colors in stanza. I hope they'll update it soon. So besides stanza, which I love and miss, what other pdf reader apps do y'all like?
