[NTG-context] clutter with \start and \stop

Hi, Say I want Tufte in 2 columns and Knuth in 1 column: --8<---------------cut here---------------start------------->8--- \starttext \startcolumns[n=2] \startsection[title=Tufte] \input tufte \stopsection \startsection[title=Tufte and Knuth] \input tufte \stopcolumns \input knuth % \startcolumns[n=1] knuth \stopcolumns does not work \startcolumns[n=2] \input tufte \stopsection \stopcolumns \stoptext --8<---------------cut here---------------end--------------->8--- It works, but isn't this a bit ugly to mix up the \starts and \stops ? In XML, that would be wrong. Is this just the normal ConTeXt way, or is there a cleaner method? TIA for any hints, -- Peter
