Nice idea… Will add it to the feature request list.
As for building it by the page navigation gadget, what I would do is make a page for each section battery, then on the main page put the link to each of those section pages.
On each section page, have a link at the top or bottom - or both (depends on the lay out of the page) back to the main page.
This way you can just quickly jump from section to section via the main page.
(Unless it makes sense that you want to look at every section every time, in which case, section 1 will have a link to main and section 2 and and so on).
