chemical structures and reactions produce wrong results. Here is one example from the wiki and two from the manual.

\startchemicalformula not \startformula
\startchemicalformula \chemical{2H_2} \chemical{PLUS} \chemical{O_2} \chemical{GIVES} \chemical{2H_2O} \stopchemicalformula
The spacing is still wrong. Compare: \starttext \chemical{2H_2,+,O_2,->,2H_2O}\blank \startchemicalformula \chemical{2H_2} \chemical{PLUS} \chemical{O_2} \chemical{GIVES} \chemical{2H_2O} \stopchemicalformula \stoptext How to mid-align the reaction? Wrapping the \startchemicalformula in \startformula works, but it's clumsy.
Also, the shorthand "+" for "PLUS", "->" for "GIVES", etc. seems to be interpreted only inline, not in displayed chemical formula mode.
I am working (with Hans) to correct the mkiv chemical code, which has been completely re-written (from ppchTeX macros). Also working on a new manual, at the same time...
That's brilliant! Marco
