We need Tex markup…
Can we have the option of rendering particular snippets of (La)TeX code? I think it would greatly help beginners with associating commands with the expected output. For example (forgive my example, I'm a beginner):
code here code here code here
The last line causes the paragraph to indent too much to the right, which looks ugly.
Having an on-the-fly LaTeX parser would allow us to see what the asker or answerer sees firsthand. The author can choose which part of the code to parse.
I imagine a two-column layout where the left side displays the code in
this style, and the right side displays the output. Repeatedly seeing a command with the expected output can help in drilling down the basics.
