The current behaviour of the Page Order tool in hiding pages is that all tools on that page have the site.upd property set on them when a page is hidden. Since it's possible to add multiple tools to a page, it may be desirable to hide individual tools on the page instead of all of them.
So there would be an extended set of options in the Page Order Helper, hide individual tools on the page, or hide the entire page (which would be all tools as it currently does).
The current behaviour of the portal is that if any tool on a page is hidden, the entire page is hidden. This would need to be modified slightly.
