Integrate schema.org support.
The new thing for search engines is utilizing schema. However, most (all?) Joomla solutions work by putting a <div> tag in the article itself, which doesn't work with F2C as it will simply be overridden the next time the article is modified. I can manually add schema code, but that's tedious. Since we're already using a form, you could allow the ability to simply link each field to a specific schema type.
