I'd really like to be able to easily tell what the original language of a book is and get stats on that. I'm always trying to read more broadly and learn about other people's experiences. I only read books in English. But some of the books I read are translated from a different language. For example, Fredrick Backman's books were originally Swedish. The Hen Who Dreamed She Could Fly was originally Korean. Manga is originally Japanese. Etc. I think it would be really cool to easily see what the original language was without having to Google it. Then I could see all the stats on that.
