My apologies.. I missed your response.
Well, the Code Magic button had to be re-written to be compatible with WP 3.9+. For this reason, at the moment, it is only available in the Pro version of WP Edit.
Regarding the switching of editor views…. you really shouldn’t be adding script tags directly inside the editor. It really messes with the final output. I would suggest using a plugin that allows you to add scripts and styles to your pages the correct way. This will keep them out of the editor; and eliminates having to worry about them getting “mangled” when switching editor views.
Again, WP Edit Pro provides easy visual interfaces to add scripts and styles on a global level, or on individual pages. Also, I’m sure you could find a free plugin that does something similar.
Hope this helps. Please let me know if you have any other questions.
