[NTG-context] more space between Chapter number and title

Hi, I am using \setuppapersize[A4] \setuplabeltext [en] [chapter=~] \define[2]\MyChapter   {\framed[frame=off,width=broad,align=middle]{#1\\#2}} \setuphead [chapter] [command=\MyChapter] \chapter{Chapter title} to successfully achieve the following result:                   1           Chapter title But I would like to have more vertical space between the '1' and the 'Chapter title'. I thought if I added [before={\blank[2cm]}] somewhere in  \framed (e.g. just before the {#1\\#2} argument, that I would achieve such a result, but that doesn't work. I also tried it as {\framed[frame=off,width=broad,align=middle,before={\blank[2cm]}]{#1\\#2}}, but that didn't work either. I am sure it is simple enough to achieve? Julian
