**Book Holder**: my VTuber model automatically "holds" any books that are currently "held" by my character in Book of Hours. There's five inventory slots, defined as "PortageSphere" slots in game, portage1-portage5. The types of items that can slot into PortageSphere slots and show up on my model: - standard readables (internal ID starts with a "t.") - journals - manuscripts - uncatalogued books **Catalogued Book Bonk:** When I catalogue a book, it bonks on my head, making it easier for viewers to see what I've just uncovered.
