I noticed (what I consider) a weird behaviour on OpanHiddenItems. It is effectively described on the commit message introducing it: Bug 10584 - Hide OPAC biblio details if all items are hidden If there are items for a given biblio number, and they are all hidden, then biblio needs to be hidden. If the biblio needs to be hidden, it immediately redirects to a 404.pl page, just as if the biblionumber does not exist. Is this a desired behaviour? Should biblios be hidden if all items they contain are marked to be hidden? I think there might be specific use cases in which this could be useful, but definitely something we should provide a way to opt-in/out I'm looking forwards for your opinions!
