Good idea, added to the code (even if the spans do nothing right now).

Using Javascript is an interesting idea, e.g. for brackets (right now
I am not able to scale them using CSS). As to MathML, I am not opposed
to it in the least, but don't know enough about it to do a good
implementation. I will add it to the roadmap in the dev guide for Q2

Done! I will hopefully release 0.39 during the weekend. Please report
any further issues, they are fun to solve!
