This is something that's been bothering me, and I've seen some people mention in IRC before. The docs are *great* if you want a full in-depth look at an API, but *awful* if you want to scan them. This provides the ability to toggle complexity freely. Interacts perfectly well with noscript, since the static page is effectively unchanged. Collapsing is just hiding divs with css.

I'm not much of a designer, so design input welcome on the actual UX for toggling.

The actual javascript is *a bit* brittle to layout changes, but it always will be without adding lots of extra junk to the actual markup, which didn't seem worth it.
