I had to modify that slightly: {{query (and (property :type book) (not (page Templates)))}}, which then gives me what I want.
Is there a way to sort the rendered list alphabetically (titles starting with A at the top, those with Z at the bottom), or would I then need an advanced query?
By default you should see the results (blocks) grouped by page and the pages are sorted alphabetically.
And in table view you should have both a “Block” and a “Page” columns that can be used to sort alphabetically by blocks and pages name respectively.
