Re-working Plugin admin Code

Hello, I have the Flashfader plugin installed,

For some reason it displays the link in the admin menu under the “Posts” section, for what ever reason this really annoys me and I want to move the link to the “Appearance” section. I’ve tried moving the link myself, but haven’t had success. Here’s the code for the admin menu link:

if(!function_exists('lynkff_addAdminMenu')) {
	function lynkff_addAdminMenu()	{
	add_submenu_page('edit.php', 'Flash Header Administration', 'Flash Header', 9, 'flashfader.php','lynkff_displayForm');
	}
}

Any ideas on what I need to change to make it move?

I’ve tried changing add_submenu_page to add_theme_page, but that just makes the link disappear.
