This extension is interesting and it seemed to work correctly but I encounter an issue.
Actually I disabled the automatic insertion of <p> in the pages. I modified text in HTML mode and saved it => OK. The <p> were not automatically inserted and the <p> I have added are on the page.
I switched from the HTML tab to the Visual tab and back again to HTML => The <p> I have added manually disappeared => Not OK
How to avoid to remove my owns paragraphs by switching from Visual tab to HTML tab?
