Hi! I'm in the process of converting some projects to LMTX. Combinations lacking “”before” and “after” keys (that place content before/after the *entire* combination, rather than the individual cell pairs), I came up with the following ugliness – which worked for longer than it deserved: \unprotect \unexpanded\def\startcombination {\blank[halfline]%% \startalignment[middle]%% \dontleavehmode \bgroup \pack_combinations_push \dodoubleempty\pack_combinations_start} \unexpanded\def\stopcombination {\bgroup\normalexpanded{\egroup{}\ntimes{{}{}}\c_pack_combinations_y}% brr \dostoptagged \egroup \pack_combinations_pop \egroup \stopalignment \goodbreak\blank[halfline]} \protect \starttext \startcombination [2*2] \startcontent foo \stopcontent \startcaption 1 \stopcaption \startcontent bar \stopcontent \startcaption 2 \stopcaption \stopcombination \stoptext I added vertical spacing and mid-aligned the content without having to change the sources, that was the idea. However, this fails in LMTX: Undefined control sequence \pack_combinations_start Does LMTX offer finer control over the combinations or do I have to rewrite the sources files (to either use floats or surround the combinations with the required commands)?
