I would like to make a "row" of a \startalign ... \stopalign "hidden". The
following fails.
\starttext
\definelayer[hiddenlayer][state=stop]
\startformula
\startalign[n=3,align={right,middle,left}]
\NC a \NC = \NC b \NR
\setlayer[hiddenlayer]{\NC a + c \NC = \NC b + c \NR}
\stopalign
\stopformula
\stoptext

There is no easy way to do this with \startmathalign, but you can try \startTABLE, with explicit values of widths. (Some day, I will check how beamer does this with aligned equations).
