restore Knol's formatting options like centering and extra fonts.
The port from Knol to Annotum preserves most of the formatting — bolding, centering, fonts, etc. — but it gets lost again as soon as you make a single edit, and there doesn't seem to be a way to get centering or anything more than sans serif fonts back.

Followup.
It appears that any attempt to edit the Knol imports in the Annotum framework reduces the formatting to utter hash.
Moreover, the function for restoring an article to a previous version doesn't work either.
