Author Customization gives you much more flexibility in managing post and page author data. Your author data will no longer be tied solely to the WordPress user system, and can now be managed on a per-post basis. Author name and description are saved with each post, allowing you to preserve this information as it was when the post was published.
Features
<ul>
<li>Per-post author display name and biographical info</li>
<li>TinyMCE (WYSIWYG) editor for user profile and per-post biographical info</li>
<li>rel=”nofollow” link inside biographical info entries</li>
</ul>

Author Customization

Author Customization expands core author management with features such as per-post author information and rich user bio editing.

AddFunc

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).
