I liked the side scrolling screen with different articles/events related to "The King James Bible." I'd love to see something like that but for different versions/editions of a book. The Bible is a good example, but also, e.g., The Hobbit has multiple extant editions. It would be cool to swipe between editions, or even search for a specific edition.
The index pattern appeared to be very well-organized and easy to understand at a glance, even for an index of indices, like the Bible. What do you plan to do, though, for a mixed index? Conceivably an index could reference a mix of other indices and individual articles. For example, a work of Shakespeare might have a Foreward, and Introduction, each an article, and then three Acts, each an index of scenes. So on each level we may have a mix or structures. We'll want to find a user-friendly way to display that hierarchy.
The profile pics for different articles in an index is a good contribution. That could be very meaningful in a Nostr-native digital magazine, for instance.
Finally, are there plans to show marginal discussions around highlight events? Maybe those can be filtered by community to create book clubs and the like.
