Unless every text line comes with <p> paragraph elements, the html view in the editor will show all html text/code cluttered. <br> line breaks are not displayed as line breaks anymore once it's been saved. This makes it a bit tiring to edit the html.
Is there any way to deactivate the WYSIWYG preview of the product editor / set the HTML view as default? This might leave the html as entered with line breaks. (At least it works like that in Magento.)
