On: LibreOffice actually works 365 days a year

The two big cad packages Solidworks and Inventor both use ribbon type menus. I think it works ok for this purpose.

Might be, but there is probably a reason other desktop ui features got much wider adoption than that.

I understand millions of people are able to use ms word. I just can't work with the UI. It even makes me angry and aggressive. And that's not an easy thing to achieve.
