Hello,
I would like to reduce the space between the numbering and the title of the chapters, sections and subsections.
I would also like to have this:

1 My first chapter
1.1 My first section
1.1.1 My first subsection

\setuplist
  [chapter]
  [style=bold,width=10mm]
\starttext
\placelist
      [chapter,section,subsection]
      [criterium=all,
       interaction=all,
       alternative=c]
\startchapter
  [title=My first chapter]
  \dorecurse{2}{\input knuth}
  \startsection
    [title=My first section]
    \dorecurse{2}{\input knuth}
    \startsubsection
      [title=My first subsection]
      \dorecurse{2}{\input knuth}
    \stopsubsection
  \stopsection
\stopchapter
\stoptext
