When I'm developing a new App and create new Modules I get the error "User provider .... Not Found" (or something similar). The .... is the name of the Module I just created. To correct this error I need to select the correct User provider, for me that is Users.
Since the default one is always incorrect (as show by the default error message) why not select a better one by default or if this is not possible, force us to choose by leaving the property empty.
I can presume that the User Provider that should be default would be "Users" for most but that is surely something that OutSystems can find out with all the metrics collected.
