Clicking an item in the side nav collapses everything else.

This is disconcerting. It shouldn't collapse things for the user.

When clicking on a link to a new page, it loads a new page session and has to run the sidebar again.

We could use localStorage to save what the user currently wants. However, but using localStorage, then there will be no solution at all the the flash of unstyled content (documented at the bottom here: #46 ) since by using localStorage, we must run the expansion/collapsing code in the client while the page is loading and shifting into place.
