Yes, a glossary list page is a feature I would consider adding. However I would want to provide a number of features and layout options for people to choose from. This would be too much to ask you to contribute.
I suggest creating a separate plugin pulling the data from the custom post type ‘wpgh-glossary’ and registering your shortcode. You can contribute by showing the implementation and/or commenting on my thoughts below (and anyone else for that matter).
Glossary List Page Ideas:
- Select the page to display list on via dropdown.
- Different layouts: list only words with tooltip hover, list words and definitions, multiple columns.
- Search
- Filter by first letter or numbers/symbols
- Pagination
- Style options?
- (Optional) Individual pages for glossary terms. Add links to glossary terms on glossary list page. Add links to glossary terms for all tooltips?
