The idea for this plugin came from a presentation at WordCamp Philly 
2011.
Code from these other plugins has served as reference and inspiration, and was sometimes borrowed from:
https://wordpress.org/extend/plugins/disable-visual-editor-wysiwyg/ 
https://wordpress.org/extend/plugins/raw-html/
Plans:
<ul>
<li>Hide the disable option from non-admins.</li>
<li>Possibly remove certain filters from the the_content filter, similar to the Raw HTML or Preserved HTML Editor Markup plugins.</li>
</ul>

Visual Editor Font Size allows you to change the font in the visual editor write field.
Once you install a plugin, you will be able to increase and decrease the font size via a 
box on the write screen.
This setting doesn’t affect the font size your users will see. It affects only you.
