View Layouts - Input Desired

i don't know isn't it better to use an output manager or something like that ?
That whole "echo" thing looks a bit weird i think.

Phil Sturgeon did a pretty good job with his Template Library imho.
Did you ever consider an option like this?

I think if a Framework doesn't provide such a functionality, i'm pretty muched get forced to develop it on my own

PHP Code:

    public function overview()
    {
        $this->template->addcss(css_app_path_relative()."frontend/index.css");
        $this->template->addcss(css_app_path_relative()."general/nav-left-content.css");
        $this->template->addcss(css_app_path_relative()."frontend/landingpage/overview.css");

        $arrNavigationData['navigation'] = Navigation_Model::getNavigation();
        $this->template->set_partial("left-navigation","layouts/partials/left-navigation",$arrNavigationData);

        $this->template->build("body");
    } 


The above example should illustrate what i mean.
