The last update took away awe.reader, one of the few readers that could split the screen for 2 pages at a time. It was free, no longer in the app store and was not restored like all the other apps I depend on. So dozens of music books i loaded into it gone with the app. Unless I'm missing something, a full back up is not full if the app is discontinued. Ok, so i do have back up of all those books. Enter Goodreader, oops, have to wait, many issues with latest update. Does anyone know of a pdf reader that has the split screen option besides Goodreader? This is not a huge deal, it is a huge inconvenience. Since when is an update supposed to destroy data?
