What's new in this version:
Version 5.1.519 has fixed bug with uploading files to Google Docs.
Navigation is SEVERELY limited on .doc, .html, etc. It loads document as a LONG 1-page document, even when MANUAL page-breaks were embedded in document. While reading you cannot simply move down ONE (current size) screen. You must MANUALLY finger-swipe to reach your specific line. Example: I have font size in .doc file such that it displays 8 lines of text. There is no real or virtual "button" (for readers without physical "page up/down" buttons) that simply moves the document down the 8 lines (1 screen's worth) to continue reading the "next page". You must manually FIDDLE-AROUND with linearly scrolling to move down that 1 screen of 8 lines. Same situation if number of lines on a screen was 30, 40, etc.
Also, if auto-rotate sensor active, if you move e-reader too much it flips portrait<-->landscape and RELOADS entire document and starts back at the beginning...LOSING YOUR PLACE.
No way to bookmark position in document.
Vertical scrollbar: only shows position in doc, NO navigation.
VERY awkward and limited navigation. Loses place. No book/place-marking.
