 STAC-Manager's [config file](/packages/client/src/plugin-system/config.ts) specifies the plugins that the app uses for Collections and Items while extending the `Default Plugin Widget Configuration` which defines the widgets for the basic field types.  
 _See the [data-widgets/config](/packages/data-widgets/lib/config/index.ts) for a list of existent widgets._
