I was too quick. Look at the distance between the integral sign and the
limits in the attached example. Is there a way to fix that?
/Mikael
\definefontfeature[mathextra][collapseitalics=yes]
\setupbodyfont[bonum]
\setupmathematics[
integral=nolimits,
]
\startTEXpage
$\int_a^b f'(t)\,dt=f(b)-f(a)$
\startformula
\int_a^b f'(t)\,dt=f(b)-f(a)
\stopformula
\stopTEXpage
