Hi Mikael, Thanks for your explanation and the example you sent about \definemathsimplealign (I didn’t get immediately that « sesac » in the command \startmathfenced[sesac] means « cases » in reverse or mirrored… I guess this is a wise and humourous choice by Hans :-) ).
Regarding \startcases, it seems that it is still not possible to number each equation, but I may be overlooking something. I’ll try a few examples and will let you know, as well as Hans.
