The blocks system is VERY un-finished but atm all you need is a view file in the /blocks/name.php and a file /blocks/name_code.php. This PHP needs to create a variable called $block_data which will be called by this function.

Its far from perfect but if you cant be bothered with the blocks, just make the $this->blocks array empty and it shouldnt do anything.

Example:

Code:

$this->template->title('Hello!');
$this->template->create('pagename', $data);

Also, if your controller is in a sub directory, it will automatically look for a header and footer file in the sub directory. Guess I should clean this lib up and release it sometime.
