Other work in progress is: better columns in itemize, esp proper footnote 
support (not that I ever need that but I know users do so ...), experiments 
work ok, but I need to check spacing. In general, footnotes (will) behave a bit 
better, especially those used nested in other mechanisms. A side effect of more 
control is that we can do other tricks too and we're playing with it (kind of 
fun).

Hi Hans,

Thanks for your explanations.

Regarding footnotes, would it be possible to have a built-in support for 
writing the footnotes in the margin? (For instance, assuming that the layout is 
such that for instance the right margin takes 1/3 of the page width, then the 
footnotes would occupy the right margin, beginning at the top).
It depends on what you want. This works ok:

\setuplayout
  [cutspace=5cm,
   width=middle,
   margin=4cm]

\setuptexttexts
  [margin]
  [] [{\directsetup{notabene}}]

\startsetups notabene
    \vbox to \textheight \bgroup
        \setupalign[tolerant]
        \topskipcorrection
        \placenotes[endnote][before=,after=]
        \vfilll
    \egroup
\stopsetups

\starttext

test \endnote{\input ward }\par
test \endnote{x}\par
test \endnote{x}\par

\setups{notaflush}

\stoptext

This one handles overflow (suboptimal, nicer is stepwise flushing) but this one also flushes notes that have refs on the next page. It just indicates the usual: most can be done in tex without too much hassle but one always needs to think about the edge cases as users can drop anything in there and all can interfere.

\newbox\MyNoteOverflow

\startsetups notabene
     \setbox\scratchbox\vbox\bgroup
        \setupalign[tolerant]
        \ifvoid\MyNoteOverflow \else
            \unvbox\MyNoteOverflow
        \fi
        \placenotes[endnote][before=,after=]
    \egroup
    \scratchdimen\dimexpr\textheight-.5\lineheight\relax
    \ifdim\ht\scratchbox>\scratchdimen
        \global\setbox\MyNoteOverflow\box\scratchbox
        \setbox\scratchbox\vsplit \MyNoteOverflow to \scratchdimen
    \fi
    \vbox\bgroup
        \topskipcorrection
        \unvbox\scratchbox
        \vfilll
    \egroup
\stopsetups

\startsetups notaflush
    \doloop {
        \page
        \ifvoid\MyNoteOverflow
           \exitloop
        \else
           \null \page
        \fi
    }
\stopsetups

\starttext

test \endnote{\input ward }\par
test \endnote{x}\par
test \endnote{x}\par

\setups{notaflush}

\stoptext

Variants (i can make one but not with this warm weather) can use selective flushing (all kinds of things are possible with notes) but another challenge is to have an independent criterium hooked into the page builder (when i'm done with playing with extensions regarding pars i might give that a go ... as usual more a challenge than a need so i need some motive).
