I'm curious why latex is weak at that? Considering most authors probably just use a notepad equivalent, the idea is if you are finding yourself having to put a ton of markup into the document, you are probably relying too much on items other than the prose to make your points.
That is to say, yes, there is a workflow. It is basically to build the prose out separately from the layout. Latex is used to typeset the document you want to do. Not to author it. By the time you get to it, you probably should be at the point where the markup is what you care about.
That make sense?
Yes, there will be times where you care about how the document looks. That is likely an iterative process and many of us find value in separating the quibbles over the look from the authoring of the content. Both are valuable. Doing them both at the same time is ridiculously hard.
