Open Library in the book store; podcast topic search and transcript search; Recipes (Mealie) with a shopping list synced to Tasks; Contacts linked to Mail and the Calendar

- Store: Open Library search, books fetched from the Internet Archive (free editions only)
- Podcast: Podcast Index discovery by name and topic (optional key); search what is said across transcripts and play from that moment
- Recipes: browse, import from a link, add ingredients to Mealie's shopping list, mirrored two ways with a Shopping list in Tasks
- Contacts: per-person address book, vCard import/export, recipient suggestions in Mail, birthdays in the Calendar
