[Analogus]

That's PRS+ for me:

• You very quick can swith off the touch-screen-paging-functionality (usefull outdoors when sitting under a tree with needles falling down or insects switching pages)
  
• Altering font sizes, fonts and page margings without altering the book before loading it onto the reader
  
• Standby mode showing actual page of the book (usefull when starring long time on the same page of a book with let's say formulas)
  
• Asign page forward function to annother button
  
• Having list of authors and notes on the home page of the reader
  
• Having the possibility to use folder structures for books
  
• Using simple scrolling in zoomed PDF's without visible scollbars
  
• Having last opened book on the home page
  
• Visible reading progress below thumbs of books on the home page
