Add its own field for "page number" apart from the titles/references/etc on panel bar
Please insert a field exclusive for "page number" in the panel view for books. The reason is to facilitate reference without having to click the box and select page number. I am aware that the page number can be selected to be visible in the text, but to the size of the screen it is not always visible.
See the image suggestion: http://imgur.com/a/LZ4s0
Make 1, take "page number" away from 2, move 3 "icons" to the side.
The field of the page number should be editable to go to desired pages.
Thanks for the help and attention!
