What would you think about adding into resources (that have page numbers) some sort of indication as to how many pages are in the whole module? Either the About This Text... info could have the total number of pages, or the display here could say Page x of y. (Just as that display can currently toggle to say Paragraph x of y.) What do you think?
I ask because each of those would be quick ways to see how far I am in a book. I know I can look on the far right scrollbar to see how far down it is--that's working for now.
