Not sure if this feature request has already been made before, but I'd love it if it was possible to be able to select one or multiple pages in the page sidebar then click-and-drag them into the bookmarks section below it so I can add multiple pages to a bookmarks folder without needing to do each one by hand via the UI menus.
Something kinda like this, but where the pages are inserted below in the appropriate area/folder on the bookmarks.
