When viewing the notes for a notebook, all notes from all notebooks are listed.
Also then routes to each are linked to the notebook being viewed each time.
Screen shows these lists for illustration:
Notebook 1: Note 1a, Note 1b, Note 2a, Note 2b
Notebook 2: Note 1a, Note 1b, Note 2a, Note 2b
Not sure if this is an issue with the template logic or the model, or mirage.
