Description

Pave navigation in TED ZIMs is very slow because everytime you change page you reload the whole page.

It is also hardly usable when you have many pages because you cannot go directly to a given page without first visiting all other pages.

You cannot go directly to last page

You cannot scroll the page selector up to the one you want to select without visiting all corresponding pages (which are slow to load).

Research direction

Start by reproducing navigation in a TED ZIM containing many pages and trace the page selector and page-reload path. Done means page changes are usable, a page can be selected directly without visiting intervening pages, and the last page can be reached directly.
