I am seeing this picture in the Extended HTML editor plugin help
To me this implies that there is a way to see the card and edit it in a WYSIWYG manner.
On top of that the plugin allows you to see the HTML code like in the picture
Am I getting that wrong ?
Also my understanding is that Anki has a default built in editor that should see the same (the rendered card not the HTML code)
It is true that you could also see that in the preview
