Run CKEditor maximized

Marry Christmas! :christmas_tree:

I investigate how to run CKEditor in maximized mode (IMHO, мore convenient: the toolbar is fixed at the top of the page) and want to share search results.

So, just add this code to Global Administration: WYSIWYG Editor ADVANCED CONFIGURATION field and save it:

CKEDITOR.on('instanceReady',
      function( evt )
      {
         var editor = evt.editor;
         editor.execCommand('maximize');
      });
