It would be a great time saver to have the Bookmark tool linked with Paragraph Styles. Many of the PDFs I create from InDesign need to have all of the headings and subheadings bookmarked. Instead of having to manually add each entry to the Bookmark panel, it would be nice to add the desired Paragraph Styles to the Bookmark panel for ID to generate the bookmarks automatically, or to have a "Bookmark" option under the Paragraph Style Options which would automaticall add the text with that style as a bookmark.
You might want to make a visit to the InDesign Scripting forum (InDesign Scripting). I suspect that it would be possible to write a script that could find paragraphs with particular styles applied and make bookmarks from them.
