Textpattern Resources mentions three WYSIWYG content editors which I built around August 2014. The trio is kuo_tinymce_cdn, kuo_jhtmlarea_cdn and kuo_cleditor. They can be downloaded from Textpattern Resources or from my Textpattern Plugins section. My Textpattern site has a download counter for files. According to it TinyMCE plugin has been so far downloaded 200 times, jHTMLArea 109 times and CLEditor 83 times.
