I wish the total number of pages of a resource was more easily accessible.
Presently, the only way I know how to find this information is to turn on page numbers as a visual filter and scroll to the end of a book.
It would be helpful to at least include this information in the Information pane for a resource.
It would be even better if it could be displayed in a way that gave the reader a sense of place and progress as they are reading a book.
