If the package whose name is produced by the active variable values is active and the variables change, then make the newly active package the one whose name is produced by the changed variables. This way, iterating through a table or a loop will automatically switch to the right package, with the exception that, if the user choses to explicitly select a different package (by clicking on its name in the packages line), then that selection takes priority. Explicit selection loses its priority when active package and active variables coincide again. I.e., one can simply "catch" the active package by activating the corresponding values.
