The method of saving the results of one app to be read in by a follow on app seems very clunky to me. Can we develop a method to use the results within a workflow to feed drop down lists in later stages in the same workflow? That way an app can stand on it's own without having to save files out and chain further apps to read them again.
It seems this only works for selecting fields to include in the output but not for list of values to feed to a drop down list.
