Allow bookmarks to control pages in the document
I use bookmarks to store documents similar to how they would be stored in a file cabinet. Occasionally, I need to move the pages withing the document which requires two stepsl, (1) move the pages; (2) move the bookmark. I suggest allowing pages to be associated with a bookmark. Once the association is made between pages and a bookmark, then when you move the bookmark to a new location, the pages would move with it. I would then extend this feature to allow bookmarks to be dragged and dropped between files.
This would be brilliant.
