When duplicating an effect it'd be awesome if the macro/modulation assignments on the original effect were copied over to the new duplicate effect. (I like going overboard with effects but keeping them assigned to a macro to adjust them all at once. E.g. the "Hyper Chorus" discussed by Andrew Wong/Mr Bill a few years back.)
(Not sure if I'm missing how to do this I've tried both cmd+drag + drop as well as right-click duplicate effect).
