When an item is highlighted within the WYSIWYG editor, highlight it within the code as well.
Since the code window displays as a large chunk of unformatted code, it should be made to function more like Dreamweaver. When an item is highlighted in the WYSIWYG editor (image, text, table, etc.) the user should be able to open the code window and see that the corresponding code is also highlighted. This would make direct code editing much easier within the built in editor.
With our plans to convert to a new Message Editor (which is now available in Bronto Labs), we are not making any changes to the existing WYSIWYG editor.
