I'm a math student, and I enjoy using LaTeX (god help me if I typeset that wrong) commands to write mathematical formulae. I'll also be needing it very soon to write papers.
The thing is, though, and this is especially true when I'm writing for pleasure rather than work, when I sit down to write something, I don't want to be staring at this:

I don't want 90% of the stuff on the screen to be typesetting commands - I want 99% of it to be my actual content. On the other hand, I loathe writing math in WYSIWYG editors, so I'd like my math mode stuff to be entirely hand-coded.
Basically, I'd like a desktop version of the math.SE editor.
Is there a way I can use LaTeX that will essentially handle everything except math for me, and just let me write the math manually by typing in dollar signs?
Note that I'm not necessarily asking for an editor recommendation - Texmaker seems nice enough. I'd be happy with maybe some sort of template system? Like I could have the boilerplate code in one file, and have it reference an external file, where I'd just type up the content. Something like that? I'm very new to LaTeX and have no idea what features are commonly available.

Is this what you mean? – nickpapior Sep 26 '13 at 13:27\documentclass{article} ... \begin{document}input{body.tex}\end{document}and then have abody.texwithout any "markup". – StrongBad Sep 26 '13 at 15:19\inputmacro which can do a lot of simplifications. :) – nickpapior Sep 26 '13 at 16:48
