LaTeX produces great looking documents, but I find it a giant pain to use.
In a word processor, an image size can be changed by inadvertently clicking on something, the style of a text selection can be changed by moving the mouse scroll wheel on the font drop-down menu, page numbering may not refresh when working on a large document, inserting a figure may screw up table or image numbering, etc. You have to be constantly checking your multi page document to make sure everything is still ok.
As a teacher, my heuristic is simple: if I'm authoring a document that is less than 3 pages, I use Word. Otherwise, I use LaTeX.
For example, I write exams and syllabi in LaTeX. Quizzes, assignments and handouts in Word. It has worked well for me for a decade.
Or type a letter, or open the document on a different computer, or set margins, paragraph size, printer, whatever.
But yes, just clicking an image won't change it.
I'm not sure what you find difficult about margins. You define them in document class. It is literally top, bottom, left, right, or height, width. Or you use the template that a publication is giving you. Are you doing something more complicated? If so, I can't imagine this is common.
Headers and footers? I never use headers. But I use footnotes (\footnote{this is all you need}).
Honestly I'm curious what issues you face. I'd gladly lend a hand (LaTeX is far from trivial) and I'd like to learn from others. But I'm honestly confused at the complaints. There's plenty of things to complain about LaTeX, but these aren't the challenges I face.
As for margins, I’ve had issues where changing the margins makes the page numbering “fall off” the page, and as for headers and footers, asserting that you “don’t need” them is not a valid option for many people producing documents.
Also to be clear, I’m not saying LaTeX is impossible or even hard to use, I’m complaining that certain tasks in it should be so much easier than they are.
The conclusion doesn't follow from the premise.
Who said "editing plain text" is more accessible (in the accessibility for people with impairments sense) than a dedicated editor that can help them with assistive technologies?
>with the emphasis being on "see" -- you must be able to see to be aware of the markup
Not anymore than you must be able to see to edit a text document. The markup can be read back to the user (and is , e.g. "bold emphasized words end bold".
Disclaimer: I'm mostly a nix user and so doing anything Word generally ends up as a pain for me, but I understand it isn't for most others.
One thing that I find useful is to have semantic line breaks in the source. That is, instead of using automatic or static word wrap, introduce line breaks at the end of sentences or clauses. This makes it somewhat more convenient to look at diffs.
