Allow changing page in fullscreen
Currently, when looking through an issue of a publication, it is a process (once the issue is found) of: click on page, click fullscreen, go back to standard screen; select another page, click fullscreen, go back to standard screen; and so on.
This could be: click on first page, click fullscreen, click or scroll to next page.
this is the main problem I have using this site for general research; if I am writing a story set in London in 1885 I want to read through the entire Illustrated London News issues for those weeks and I can see the full page on my 27" 5k monitor in full screen. Just as the OP has put it I have to back out of fullscrre before I can go to the next page. it wooly also be nice if 2 facing pages at once could be displayed as the illustrated publications often did full 2 page pictures on their middle pages. Just provide a protected click area at the right and left edges of the fullscreen for next or previous page.
