It would be nice to have one of those functions available. Like I said in my first thread in the development forum, I'm currently hacking the chicane template and I would feel a lot better and safer if I could move the header/navigational part to a separate php file to be included in the individual pages.
As I think this is best and most quickly done by someone familiar with the php scripting engine, I post this as a feature request rather than trying to implement it myself
