Hi, amsmath provides an environment `flalign` that flushes the "block" for display math. See page 6 (pdf page 27) of my article on display math in context (https://www.ntg.nl/maps/34/06.pdf) for an example. As shown in that article, I could achieve the same behavior in context mathalign by using distance=2em plus 1fil. However, on a recent context, the glue gets ignored. \starttext \startformula \startmathalignment[m=2,distance=2em plus 1 filll]%Notice distance=... \NC \nabla\cdot \bf E \NC= \frac{\rho}{\varepsilon_0}, \NC \nabla\times \bf E \NC= -\frac{\partial \bf B}{\partial t}, \NR \NC \nabla\cdot \bf B \NC= 0, \NC \nabla\times \bf B \NC= \mu_0{\bf j}+\varepsilon_0\mu_0 \frac{\partial \bf E}{\partial t}. \NR \stopmathalignment \stopformula \stoptext Looking at math-ali, I cannot figure out why that is happening.
