Code to get a plugin to

[kh99]

I'm not sure what you mean by "automatically make a custom powered page", can you explain that more?

You could probably add a link to the navbar using the hook build_navigation_menudata and adding to the $menudata array, but I don't know exactly what you'd have to add. If I were going to do it I'd start out by printing the existing $menu (using print_r(), for instance) and seeing what the structure looks like.
