@jeremyruston From my point of view “caption” is the wrong field to show. As captions used at the moment they are short. Titles are not.
In the TOC-rewrite which is described at: TOC-macros Rewritten (+ a lot of new fuctionality) - Part 2 I did allow the TOC macros to select a captionField
which should be used instead of caption.
If captionField does not exist or is empty, it falls back to “caption” and to “title” if needed
In my own wikis I do use a field named: subtitle that can be shown as a title in a ViewTemplate.
My uni-link plugin allows link shortcuts that show caption, subtitle or any other field-name alongside case insensitive aliases to be shown in pretty-links.
So showing caption as the only alternative title in a core view template is not generic enough. It’s specific to linonetwo’s usecase.
