I'm a Mac OS X user of Acrobat X.
On the Windows platform I know there is that plugin tool "autobookmark" for semi-automatically creating bookmarks and named destinations. This tool is immensely useful for creating bookmarks for PDFs and maybe even for OCR'd scanned files.
I'm trying to look for a Mac platform equivalent. Is there one? What do Mac users of Acrobat X recommend? The built-in Acrobat X bookmarking tool is very basic and too "manual" to use for a large document like a technical manual or some large scanned files.
