Add ability to name pages, and more crucially ability to scroll though pages (e.g. as in adobe pdf viewer)
It is extremely difficult to manage a document with large number of pages. Please add ability to name pages. And ability to scroll through them in some way. This can be done as in iannotate pdf with the list and preview of pages on the left, or instead of previews, simply a text list of pages and their names. Or simply as the adobe pdf viewer with a scroll bar on the bottom.
