The page index stays with you
A document with sub-pages shows an index of them on the left. Until now that index listed the page you were on — so it was there on the document's root page and gone the moment you clicked into a sub-page, which has no sub-pages of its own. You landed on the sub-page with no index and nothing telling you where in the document you were.
The index is now the Space's whole tree, on every page of it. It is rooted at the Space —
Infrastructure, say — and every page beneath it shows the same index: the Space's pages in their
order, a page with sub-pages as a collapsible group, the groups on your path open, and the page
you are reading marked with the accent bar. Clicking into a sub-page keeps the index and moves
the marker; a page directly under the Space, such as Infrastructure/Options, shows it too. A Space
with a single page and nothing beside it still renders full width, as before.
Two pieces of chrome came with it:
- The divider drags. The line between the index and the content is a real resize handle (180–480px). It was meant to be all along; a rule that hides the chat panel's divider when that panel is closed was written broadly enough to hide this one too.
- A button in the top bar hides the index — beside the logo, where a browser keeps its sidebar button. Hidden, the button turns into the one that brings it back, and your choice follows you from page to page and across reloads. The button appears only on pages that have an index.
A course keeps its own index (the whole course, in the course's order) and gains the same divider and button.
