Perfectly clear now.

I think that offering a good initial user experience is very important (even if the target audience is developers enjoying hacking).

Btw, related to this subject, should we consider reviewing the usage of “showtitle” and “notitle” as well? When you read the documentation is clear that they apply to different scenarios, but having two options with opposite meanings it's weird to me.

For instance, we could use showtitle always, but set it to true by default when footer_header is true, and false otherwise.
