Besides the two points listed above, another thing left is to:

• reduce / eliminate the custom code executed on save action so that the real-time relies on the standard action buttons behavior as much as possible (which will simplify the integration with the in-place editor)

Besides this, another thing that needs to be done, probably in a separate issue, is to separate the code specific to CKEditor in separate JavaScript modules in order to have a clear view of what is the interface / contract between the real-time editing and the WYSIWYG editor, i.e. to know what we need from a WYSIWYG editor in order to integrate with it.
