@derek This is a bad take. Don't blame the word processor for all the deficiencies you've pointed out. Blame the way it's being used. When I'm composing in a word processor, I have all my styles pre-defined. I'm never concerned about the the body text, or the heading text, or any other attributes. All I really do is organize my sections and write.
@derek Listening to the way you talk about leaving markers and complaining how word processors don't give you a way to do that illustrates the problem that you don't know how to use styles. That's exactly the problem styles in all word processing programs are meant to solve.
