AutoBookmark ($189 or $99 each in a 5 license pack) is an Acrobat plug-in (Windows only). It adds a menu item and a panel to Acrobat. A free trial is available if you want to check it out.
AutoBookmark is my go-to Acrobat plug-in tool for managing complex projects with a lot of bookmarks and links. You can easily copy bookmarks between files, create bookmarks from headings or Bates numbers and about a hundred other features.
It’s a great tool to have if you prepare sets of linked exhibit files in complicated cases.
The latest release of AutoBookmark can (ta-da!) create a Table of Contents from Bookmarks in your document.
Adding a TOC to your PDF makes it easier to navigate and it looks great, too. It’s a requirement when creating closing binders and final document sets.
