NEW - xbFootnoteTag Package Release
v1.0.1 now available. The package contains a content plugin and and editor button. The button inserts and {xbref...} shortcode and the plugin converts the specified tag description into either or both a popover or a footnote.
So collect all your references for your site into tags and then you can use them as footnotes in any article. Or use it for definitions and acronyms - define them once and add in any article. Plus many other features.
