[NTG-context] marginal heads as standard option?

Hans, I have the following sample: \setuphead[section][alternative=margin] \starttext \section{afeasdf} \input knuth \section{afeasfdf} \input zapf \stoptext Would it be possible to have value to the "alternative" key that automatically places the head on the margin? I mean, not only the number, but the whole title. Probably this option should allow the user to set head in the inner, outer, left and right margins. I know that it should be possible with an extra command, but consider that "reverse" is also a value for the "alternative", Many thanks for your help, Pablo -- http://www.ousia.tk
