I understand that because of different devices, screen sizes, font sizes and other personal preferences it’s “supposed” to be difficult to implement a page numbering systems. The problem is that we don’t really need a page numbering system, but a page number reference that corresponds to the printed book. So whil I understand a hypothetical Page 75 could be position 248 or maybe 23% progress of the book, it would be nice to have the reference so that when an instructor tells you to turn to page 75 you can jump to the location of the ebook that he’s speaking of and navigate more easily. I don’t care tht it’s position 248, what I care about is when an instructor is on page 75 and starts reading the first lines of that page I can find it faster than trying to guess what the position number or percentage of progress I’m at…. For instance I have to read Glenn Greenwald’s No Place to Hide and page 95 starts at the top of the page “This self-imposed mandate requires…”, the Kindle app, no matter what platform or personal settings could have a small icon that represents a page number and tapping, touching, or mousing over it would show the printed page reference… with my current settings the app shows 36%, Location 1636 of 4619, the status bar at the bottome could also say printed page location 95 and it changes accordingly… why can’t that be implemented in future updates? Otherwise I like all other features of the app… just wish it was more friendly for students...
