Automatic equation numbering

When selecting "Include Mathjax", it'd be good to have an option to include this script (http://docs.mathjax.org/en/latest/tex.html#automatic-equation-numbe...) in the html header:

Probably the script can be included anywhere before invoking Mathjax.

Once it is included, equations can be numbered automatically and linked using labels. I have included two files showing how to number and link equations in markdown and the modified html file.

Obviously it would be better if the equation numbers and links would be visible in Marked.

   Do you think this is something that would be widely used? I only ask because I have little knowledge of equations and their uses in documents, and have no idea what the specific situations where this would be required are.

   I think that this feature would be quite useful for students, teachers, researchers who are dealing with math, like physicists, chemists, statisticians , etc.

   In my case, I'm planning to move to markdown the notes of one course I teach on process control and it's something I really need, a lot of equations there.

   I don't know how much time you would need to invest to implement it. As far I know is something that isn't available in any markdown edit (at least for mac).

   Shouldn't take too much time, it's just another checkbox in preferences
   that I need to fit in without making it messier. It does sound like
   something useful enough to consider.

   Maybe something like this:

   ⬜︎ Include MathJax ⬜︎ Automatic equation numbering

   I think that there is enough space there. The option "Automatic equation numbering" would be grayed if "Included MathJax" is unchecked.

   I also have exactly same wish with Javier.
   Now, I am using Marked2 with scrivener for my thesis.
   The equation numbering is definitely needed for student.

   So this setting can be set to "AMD" or "all". See docs at:
   http://docs.mathjax.org/en/latest/tex.html#automatic-equation-numbering

   Which would be more useful?

   And note that you can use this at any time (when MathJax is enabled) by just adding:

    <script type="text/x-mathjax-config">
    MathJax.Hub.Config({
      TeX: { equationNumbers: { autoNumber: "all" } }
    });
    </script>
   

   at the end of your document.

   Thank you for your quick reply.
   Actually, when I convert my scrivener text to latex, I am using "AMS" style numbering.
   I tried the above script with "AMS". But Marked doesn't show math equation with that option.

   <script type="text/x-mathjax-config">
   MathJax.Hub.Config({
   TeX: { equationNumbers: { autoNumber: “AMS” } }
   });
   </script>

   No, the only way I could get numbers to show up was to set it to "all,"
   but I don't know how it all works…
