Actually it looks like a version of this is currently possible! There’s a handle in the lower-right corner of the equation editor that let’s you resize it. Once you’ve done that, it remains at the set width and wraps the contents to fit. The way the equation editor follows the cursor can be a bit janky, but it does seem to work.
Yes, that is right.
I don’t have any recent examples in the EA Forum, but here is an article I wrote in LessWrong where the equations where very annoying to edit.
I expect I occassionally would use larger equations, better formated (with underbraces and such) if it was easier to edit in the WYSIWYG editor.
