Hello,
I need to save some phrases from many book.I insert the book in my library and after I create many Notes as many Phrases I need to save.Each note have his single or multiple tag.

Into my Mac app, when I select a Tag in the sidebar, on thew right I see the Books that have some Notes with the tag, and the Notes with the correct tag selected have the title white, the note without the selected Tag have a grey title.

Into the iPad app, the app show me all notes related to the book that contain the selected Tag!

I think this is a bug
