It would be great, if there was a “info”-field that could contain wysiwyg (html, text + images) and the field would be editable only in the “Field Group” -editor.
In page/post edit view it would only render as in static html.
This could help us create info areas for content editors.
You can enter html into a message field. It’s not a wysiwyg editor but it works. You can compost the content in a wysisyg editor and then paste it in.
