The existing Switch action allows you to define logical branches for possible values of a workflow variable, but those values are explicit numbers or strings. My suggestion for an improvement would be to allow these values to be variables. For example, if I have the variables TESTME, N1, N2, and N3 then I'd want to be able to build a Switch statement that tests the variable TESTME against the values of, N1, N2, and N3 and selects the matching branch (as long as these are unique values).
