tinyWYM Editor was created to help inexperienced WordPress users create cleaner, more semantic markup, and to avoid some of the pitfalls of WordPress’s standard WYSIWYG editor. It does this by labelling and highlighting all HTML elements in the editor, creating a visual representation of the HTML being generated.
tinyWYM Editor also gives more experience users all the control and flexibility of the text editor without having to leave the visual editor. Create and edit any HTML element, add attributes, and wrap or unwrap elements all from the visual editor.

At long last: Now we can see the container hierarchy while editing visually, and manipulate it too!
The plugin author is quick to respond, clear friendly and helpful.
Unreserved recommendation!



Fantastic

Convert WordPress's WYSIWYG editor into a WYSIWYM editor. Add and edit any HTML tag and attribute from the visual editor.

AddFunc WYSIWYG Helper is a lightweight plugin that uses CSS to highlight prominent HTML elements in the default WYSIWYG editor (Tiny MCE), to help Editors see what they’re editing. This in effect creates a sort of combination WYSIWYG/<a href="http://mcs.open.ac.uk/nlg/old_projects/wysiwym/" rel="nofollow ugc">WYSIWYM</a> (What You See Is What You Mean) combination. With the WYSIWYM option turned on in your user profile, the following elements are highlighted with a colored border and label:
<ul>
<li>p</li>
<li>div</li>
<li>pre</li>
<li>ol</li>
<li>ul</li>
<li>li</li>
<li>figure</li>
<li>article</li>
<li>section</li>
<li>aside</li>
<li>header</li>
<li>footer</li>
<li>span*</li>
<li>code*</li>
</ul>
*Span and code elements are highlighted without labels. For span elements, this is to help make them more prominent, so they are easy to spot. This can help Editors keep the code clean, as they can see where they need to remove unwanted styling using the style eraser button. For code elements, we do this because WordPress apparently always wraps these within another element, treating it as inline, rather than a block. The labels can only be workable on block elements.
Your theme can still apply an editor-style.css stylesheet. In most cases, the WYSIWYG will still reflect how the content will look on the front end of the live website.
AddFunc WYSIWYG Helper also provides an option to cancel out certain default styles in the WYSIWYG, such as the caption box/border.
Unlike it’s predecessor, Average WYSIWYG Helper, these settings are not on a universal options page that applies to all users. Each user can enable/disable these options on his/her user profile settings page under the heading “WYSIWYG Helper”.
Note: It is suggested that Editor’s using the WYSIWYM use a browser that supports CSS3 for best results.

A good plugin if you are searching for such a function.



Works as intended

Highlights prominent HTML elements in the WYSIWYG editor, to help Editors see what they're editing. Sort of a WYSIWYM (the M is for mean).
