Hitch, your defense of Word and WordPerfect betray your life as an editor. They aren't good tools for an author, however, because writing isn't linear. See Rob Sawyer's explication at
https://sfwriter.com/wordstar.htm for why he and I and other writers never understood why people opted for WordPerfect over WordStar in the 1980s/1990s.
Word can be kludged, of course, with a WordStar command set written by Mike Petrie, who also maintains a WS website. That's how I use Word, though I have little interest in styles. It's so easy to clean up Word's awful html! Why waste time adapting yesterday's styles to today's book?
Just FWIW. I realize this doesn't apply to your line of work, and perhaps not that of anyone else here. In college I learned to compose on a typewriter, but I always had a yellow lined pad at hand when things got tough. The day I discovered "computer" composition (an Olympia electronic typewriter with a computer extension with a 5.25 inch disk drive) was a joyous one, March 1985. I sold that piece for $250 and never looked back. At last I could massage a story or essay until it just FELT GOOD, and only then print it out -- and mail it, of course! It was several years before editors would accept a computer disk (or many disks, in the case of a book).
