The Gramps Glossary is slowly (over the last couple years) being enhanced as a way to cut down on obscuring detail in wikipages.
The plethora of pages that explained Core Concepts had become a maintenance nightmare.
Rather than repeat something like how to change the Home Person (and explain the concept & purpose of a Home Person) each time it is mentioned in the manual, we can just link Home Person to the Home Person Glossary term.
People familiar with the concept don’t have to wade through excessive detail. But looking at the glossary term will give a short definition, it also links to the detailed introduction and usage.
