I just tried this:
... you may still tell the $pages->find() to sort by the parent's order by specifying "sort=sort" in your selector. This is the same as saying "sort by whatever order I dragged the pages to in the admin." But note that if the results have multiple parents, the resulting order isn't likely to be useful.
The grey bars are the titles of the parent pages (to be exact, the parents of parents) ... somehow this does not seem to be sorted as in the admin ... ?? If it was as in admin, surely they should be grouped by common parents?
How can I group all the results by the parent pages? I.e. how can I make the find() return the pages as they appear in admin order?
