It would be helpful to have actual author pages. Currently author links just go to search results like Japanese Books Difficulty List | Natively (吉屋信子) - which mostly works, but some authors pick stupidly generic and short pennames (sometimes even a single kanji) that will result in a ton of unrelated hits
At the very minimum, it could simply list their available titles. Though it might be interesting to list autobiographical information, which I think Amazon usually has (idk whether available via API)
