Hide finished iBooks? I have a lot of books in ePub and PDF format in iBooks on my Mac. I sync the next few ones I want to ready to my iPhone and iPad and read them there.

Is there a way to set up a workflow so that when I finish reading a book, it "goes away" from iBooks, everywhere? I'd like the list of books to keep shortening so that once I'm done reading a book, I don't see it anymore.

It seems like a natural feature to have in a book reader, to not see books that one has already finished reading. Syncing of current page works great across all my devices, but automatically hiding / deleting read books is something that I'd like to have as well.
Why not put the finished books in a folder?

That’s an easy way to get them out of the way. Also, since you are on a Mac you can easily export / delete / file them outside the app so you have a backup that’s easy to manage and a clean slate for new reading.
