Thread:Extension talk:WYSIWYG/Edit text of nowiki and syntaxhighlight tags directly in wysiwyg mode as text (without using image- elements)

I am trying to modify wysiwyg so that it would be possible to edit texts of nowiki and syntaxhighlight tags directly on page as text in wysiwyg mode. I am trying to use combination of    .......  and html tags for this.

Any ideas / comments about how to do this properly are welcomed here: Github#50?
