This looks very good; among other things, it even auto-converts 1) deep links during editing (preview before saving wiki changes) to 2) deep links once the wiki is saved.

One slight issue: if I include a deep wiki link in a regular post--say, to point someone to a specific wiki section--the interface opens a new window with that section at the top, but with the wiki still contracted. Clicking on "Click here to display full wiki" opens the full wiki, but scrolled back to the top.
