In editing content, can I show source formatted HTML Might there be a way to show properly formatted HTML when in CKeditor's source view? Is there a way to color code the HTML and Javascript source for my more advanced content editors?

I have turned on Apply Source Formatting which has helped some.

There is most likely more plugins available but you will need to add a plugin to achieve what you are looking for.
