You mention that jsMath doesn't process some macros like \dfrac. These are part of the amsmath LaTeX package, and jsMath does handle those, but they are not loaded by default. It would be possible to request jsMath's AMSmath extension to be loaded for all problems, or to define the macros you are most interested in so that they autoload the AMSmath extension.

The first could be accomplished by editing the webwork2/htdocs/jsMath/jsMath-ww.js file and adding

    Setup: {
UserEvent: {
}
},

    Font: {},

This would cause the AMSmath extension to be loaded for every problem for every class (but since the file should be cached by the browser, that is not such a big deal). I should add a variable in global.conf that gives an array of extensions to load automatically to make this easier for you.

    dfrac:       ['Extension','AMSmath'],

    boldsymbol:  ['Macro','{\\bf #1}',1],
