This is a frequent problem with Calibre - where can we edit, via the main interface, multiple authors? An example: recent edition of "Siddhartha" by Herman Hesse, translated by Joachim Neugroschel. There is no location in any Calibre screen to edit "translator" so when the file is viewed in a Kobo OR Freda epub reader, the *author* is incorrectly listed (and indexed) as "Neugroschel." Where/how can we view or add "editor" and "introduction by" and "translator" fields to the main Calibre "edit metadata" screen to be able to edit problems like this?
