hansbkk I have introduced myself in the appropriate forum http://forum.dokuwiki.org/post/28124, feel free to skip the personal details, but I also asked a substantive question in the second half, probably best to answer here?
hansbkk I sent a heads-up to author of SubjectIndex, and he almost immediately replied via email. Summarizing his response here FYI ---------------------------- SubjectIndex plugin, was intended for exactly this, creating multiple index databases and pages. You can customize the ordering if the A-Z default isn't sufficient. There are many options documented in the instructions. Regarding navigation, note the breadcrumbs/Trace history. Not currently aware of a plugin for your Home/Up/Back request. . .
