Attempting to add a plugin to tinymce for a wordpress plugin I am creating

Hello advanced wordpress community.

I am attempting to make a plugin (modify really and will release it to the community here).

In this senario, I need the plugin to modify a text box using the native wordpress tinymce with one addition, I want to use the tinymce fullpage plugin normally included with a standardard tinymce install.

to add the tinymce full page plugin i have tried adding the following:

	function myformatTinyMCE($in) {

		 $in['toolbar1']='bold,italic,strikethrough,bullist,numlist,blockquote,hr,alignleft,aligncenter,alignright,link,unlink,wp_more,spellchecker,wp_fullscreen,wp_adv ';
		 $in['toolbar2']='formatselect,underline,alignjustify,forecolor,pastetext,removeformat,charmap,outdent,indent,undo,redo,wp_help ';
		 return $in;
		$settings = array('textarea_name'=>'template');
		wp_editor( get_option('html_template'), 'htmlemaileditor', $settings );

However upon inspection doing that makes it so that tinymce is looking for the tinymce fullpage plugin that does not exist. I then tried downloading tinymce and extracting just the fullpage plugin directory and placing that plugin in my wordpress plugin i am creating at the path "/fullpage_plugin/plugin.min.js". I then tried referencing it doing the following:

add_filter('mce_external_plugins', 'myplugin_register_tinymce_javascript');

function myplugin_register_tinymce_javascript($plugin_array) {
   $plugin_array['myplugin'] = plugins_url('/fullpage_plugin/plugin.min.js',__file__);
   return $plugin_array;


It is indeed seeing the file, however for some reason tinymce is still looking for the plugin at:


Any experts out there know of a way to get this working...? I am modifying the html email plugin in a way that I think everybody will enjoy.
