This is not an improvement wrt Microsoft Word, which uses classes for things like lists instead of tags like <ul> and <ol>. Why? must ask Microsoft…
It would definitely be a big plus to get Word working… Word and Docs are the two most popular word processors in the world…
EDIT: Check out HTML EDITOR.in: Free Online WYSIWYG HTML and HTML5 Editor which seems to have it working. It converted from complex Word documents quite fine!
Ironically, this version: HTML EDITOR.in: Free Online WYSIWYG HTML Editor which uses TinyMCE chokes on the bulleted lists, indicating custom logic in the original converter.
