This might be an edge case and not that important, but I have a some cases where I have read or want to read different editions of a book (e.g.: want to reread it in another language) and there's only a link to one of the editions. So it would be nice to see them grouped somewhere, for example as the top editions in the browse editions list.

It might also be nice to see the editions you have tagged or marked as owned (but not marked read or to-read yet) at the top of the list.
