It is quite easy to integrate the Open Source HTML-Editor tinymce into the code generated by phprunner. However, when doing that, all textareas in the form are handled by tinymce.
The editor can be configured in that way that only the <textarea> Tags with a specific class attribut are handled. Would it be possibly to integrate tinymce support into the next version of phprunner? That would require only an extension to the "Edit as" settings. When choosen "HTML editor" there has to be added a "class" attribut to the textaerea tag.
