Feature, add nested bookmarks, and make bookmarks remember page location and zoom.
To match nested TOCs, especially when the outline is not editable, it would be nice to have nested bookmarks. The "parent" bookmarks should still work, i.e. not bookmarks in directories like Firefox, so bookmarks would be able to model the outline.
Also, bookmarks should remember exact location within page, much like Firefox's PDF bookmarks.
