Features of this WordPress glossary tooltip plugin:
Automatic term detection – Scans post content and automatically identifies glossary terms without manual shortcodes
section exclusion logic – Prevents tooltip links from appearing inside sections where the term is already defined as a heading
Multiple glossary posts support – Fetches and processes all posts from the “glossary” category
Multi-word term matching – Sorts terms by length (longest first) to properly match phrases before single words
Tooltip Display Features
Positioned tooltip box – Fixed-position tooltip that automatically adjusts to stay within viewport boundaries
Tabbed interface for multiple definitions – When a term has multiple glossary entries, displays as tabs with unique titles
First vs. subsequent occurrence styling – First occurrence gets highlighted styling (pink, bold), subsequent occurrences have italic styling (black, normal weight)
Smart viewport positioning – Automatically positions tooltip above or below term based on available screen space
Mobile responsive – Adjusts width and layout on screens under 600px

Click-outside-to-close – Clicking anywhere outside the tooltip closes it
