In reply to Wil Ransz.

Here is an update to my comment above. The new DFW feature had become increasingly annoying to me. The past two weeks, I have been checking out alternatives. Within WordPress as well as outside of WordPress.

Today, I have settled for TinyMCE Advanced with a minor addition. The default DFW mode of TinyMCE Advanced is screen width. So, I have created an editor-style.css, and uploaded that to the theme folder. The editor-style.css has only one rule: .mce-content-body {max-width: 600px;}. For me, this is a workable, and distraction free solution.

Please note that you have to enable the editor-style.css within Settings >> TinyMCE Advanced >> Advanced Options.
