In Calibre, how can I:
-Easily mark a book as "read".
-Hide read books (or unhide them) when viewing a list of books (for example, I would like to be able to hide read books when viewing all books, or books by a single author

I can add a 'read' tag if needed, but using tags to view/hide read books appears to require writing a custom search for each view, which is too cumbersome.
