Would be great. I have a large audible library, so all I have is the ASINs and it's a hassle to add them all manually. Always have to check the existing audiobooks for potential matches (i.e. books with a missing ASIN), then check Goodreads (often their data seems to be outdated.. loads of non-/no longer existent ASINs) and ultimately grab all data to enter it manually.
Still have about 220 books with no matches in hardcover

That would be amazing, because I have books that have only been published as e-books.
