Eldorado Superfly is a module that takes control of the "Submitted by..." text, node links, user pictures, and comments. It moves them to $node->content, where they can be re-ordered on CCK's Manage Fields tab. However, this means they are no longer under control of the theme.
Adds ability to change theme for specific node.
