Using stash to move safecracker JS to footer

example.html

{exp:safecracker channel="foo" include_jquery="no"}
	{exp:stash:set name="safecracker_head"}
	{safecracker_head}
	{/exp:stash:set}

	......

{/exp:safecracker}

......

<script type="text/javascript" src="/js/jquery.min.js"></script>
{exp:nest parse="inward"}
	{exp:stash:get name="safecracker_head"}
{/exp:nest}
</body>
</html>

Nest.php

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

$plugin_info = array(
	'pi_name' => 'Nest',
	'pi_version' => '1.0.0',
	'pi_author' => 'Rob Sanchez',
	'pi_author_url' => 'http://github.com/rsanchez',
	'pi_description' => 'Useful when you need to delay the parsing of the inner, nested tag.',
	'pi_usage' => '{exp:nest parse="inward"}
	{exp:other:tag}
{/exp:nest}',
);

class Nest
{
	public $return_data = '';

	public function Nest()
	{
		$this->EE =& get_instance();
		
		return $this->return_data = $this->EE->TMPL->tagdata;
	}
}

Actually, with the latest from the dev Stash branch you can do this without the nest plugin:

{exp:stash:get name="safecracker_head" process="end"}
