Every page? That is an administrative nightmare! That is not the right approach anyway. I made a mistake in that the breadcrumb trail is based on menu selections. So the example breadcrumb should be Braun -> Intro (an actual page and is a URL link) -> Experiment Systems -> MiniSystem (which is the actual page). Braun and Experiment Systems are NOT pages, they are menu placeholders. Intro is an actual page as well. I will send you a screen shot of the menu design for this tree.
Thank you for being such a flexible and responsive plugin author. You are a rare breed to be sure!
