How to scroll pages 1,..,N-1 and show page N in PDF viewer?

I want to show two pages of a pdf document at the same time in PDF viewer such that 1. be able to scroll pages 1,..,N-1 at the left-hand-side view 2. show all the time page N at the rigth hand-side view The reason is that I am inputing data on pages 1,..,N-1 from the user, while the page N aggregates the data on page N. So I want to show all the time the last page. Maybe, it is possible somehow in some internet browser. OS: Debian 9 PDF viewer: any PDF viewer, but preferably Adobe acroread with Javascript installed like here Internet browsers: Firefox 52.2.x, Google Chrome 59.x
