In this note we consider unimodality problems of sequences of
multinomial coefficients and symmetric functions. The results
presented here generalize our early results for binomial
coefficients. We also give an answer to a question of Sagan about
strong $q$-log-concavity of certain sequences of symmetric
functions, which can unify many known results for $q$-binomial
coefficients and $q$-Stirling numbers of two kinds.
