Hi,
I wrote two new imposition formats with chngeable size.
The first format could be used to create flashcards with content on
both sides of the paper. The number of cards on the page could be
changed with the "nx" and "ny" keys for \setuppaper.
\unprotect
\installpagearrangement FLASHCARD
{\dosetuparrangement\@@ppnx\@@ppny{\numexpr\@@ppxy*2\relax}{\numexpr
\@@ppnx+\plusone\relax}{\numexpr\@@ppny+\plusone\relax}%
\pusharrangedpageFLASHCARD\poparrangedpagesAB\relax}
\newcounter\arrangedpageshiftX
\newcounter\arrangedpageshiftY
\def\dopusharrangedpageFLASHCARD#1%
{\ifnum\arrangedpageshiftX<\arrangedpageX
\ifodd\arrangedpageN
\handlearrangedpageXandY{#1}0\arrangedpageshiftX
\arrangedpageshiftY\arrangedpageA \else
\handlearrangedpageXandY{#1}0{\numexpr
\@@ppnx-\arrangedpageshiftX-1\relax}\arrangedpageshiftY\arrangedpageB
\doglobal\increment\arrangedpageshiftX \fi
\fi
\ifnum\arrangedpageshiftX=\@@ppnx
\doglobal\newcounter\arrangedpageshiftX
\doglobal\increment\arrangedpageshiftY
\fi}
\def\pusharrangedpageFLASHCARD#1%

\dopusharrangedpageFLASHCARD{#1}%
\doglobal\newcounter\arrangedpageshiftX
\doglobal\newcounter\arrangedpageshiftY
\poparrangedpages
\else
\dopusharrangedpageFLASHCARD{#1}%
\fi}
\protect
\setuppapersize[A7][A3,landscape]
\setuppaper [nx=4,ny=2]
\setuparranging[FLASHCARD]
\setuplayout [location=middle,marking=on]
\setupbackgrounds[page][frame=on]
\starttext
\dorecurse{20}
{\startstandardmakeup[align=middle]
Front side \recurselevel
\stopstandardmakeup
\startstandardmakeup[align=middle]
Back side \recurselevel
\stopstandardmakeup}
\stoptext
My second imposition definition could be used to create leaflets of any
size, the number of rows is fixed to 1 but the number of column could
be changed with the "nx" key for \setuppaper.
\unprotect
\installpagearrangement LEAFLET
{\dosetuparrangement\@@ppnx1{\numexpr\@@ppnx*2\relax}{\numexpr\@@ppnx+
\plusone\relax}2% \pusharrangedpageLEAFLET\poparrangedpagesAB\relax}

\handlearrangedpageXandY{#1}0{\numexpr\arrangedpageN-\@@ppnx-2
\relax}0\arrangedpageA \else
\handlearrangedpageXandY{#1}0{\numexpr\arrangedpageN-2\relax}0
\arrangedpageB \fi\fi
\ifnum\arrangedpageN=\arrangedpageT
\poparrangedpages
\fi}
\protect
\setuppapersize[DL][A1,landscape]
\setuppaper [nx=3]
\setuparranging[LEAFLET]
\setuplayout [location=middle,marking=on]
\setupbackgrounds[page][frame=on]
\starttext
\dorecurse{6}
{\startstandardmakeup[align=middle]
\ssd Page \recurselevel

I hope both arrangment styles could be integrated in one of the next
releases, the FLASHCARD style is a must have for me because I use it
sometimes and I'm not interested to always define one of these styles
in my document.
