add bookmarks to the Viewer
Every time I close a multi-page document in the Viewer I lose my place - it'd be great if I could place a bookmark (with or without a name), especially for those long documents.
The "Place Bookmark" button could be in the Tools or Navigation section and the Navigation bar could allow you to scroll between multiple bookmarks, the way you scroll between pages and docs.
Your idea has been added to our backlog. We are now further investigating the idea.
