Hi, I think what you ask for was never supported in ConTeXt, for a reason. The idea is that either one groups a set of equations with a brace and numbers them with one number, or one does not group, and then one can number each line separately/independently. Grouping on the left with a brace and numbering one line to the right is, even if we see that often, not really logical.
If there is a large request for doing this, I can talk to Hans about it, maybe it is easy on the code side to support it. But I remember from when we were messing with numbering, and in particular when there are alignments, that it is a bit complicated. /Mikael On Wed, Oct 9, 2024 at 5:19 PM Alan Bowen <bowenala...@gmail.com> wrote: > > Thank you, Mikael.
