WYSIWYG editor – how to add back Visual/Text tab

Hi all,

First, thanks for the great plugin.
I want to add back Visual/Text tab for WYSIWYG editor. I have checked official document, it said “The Wysiwyg does not feature the standard “Visual / HTML” tabs above the editor. Instead, the html can be viewed and edited by the “HTML” button on the second row of toolbar buttons.”

But i really want to add back this feature, even modify the plugin files, how can i add it back? thanks
