[NTG-context] ToC - right-alignment of roman numerals

Dear All, in fresh MkIV I use the following commands for building ToC, but I have no idea how to align the label (roman numeral) to the right. In addition, the specified width and distance seem to be somehow ignored so that label interferes with the title. \setuphead[chapter][conversion=Romannumerals] \setupheadnumber[chapter][48] \setupcombinedlist[content][ alternative=c, distance=1em, width=3cm, ] \starttext \completecontent \chapter{Foo} \chapter{Bar} \stoptext Here is the link with several screenshots of desired formatting: http://tex.stackexchange.com/questions/69559/align-the-roman-numbers-of-the- parts-in-toc Any hint is appreciated. Thanks, Jan
