Adding code to test each filter class to make sure the filter is emitting the proper signals during its preflight function.
Inserting the template documentation for these filters and marking them as experimental until the documentation is written.
Adding new signal to this Widget to emit when a file is dropped. This will allow other widgets that use this widget to tell when someone drops a file or simply typed something in the widget.
Adding a qDebug() output for each widget if it fails to set the value into the filter. Hooking up the signal of a file being dropped onto a QLineEdit for the InputFileWidget. This same should be pushed out to the other file/path type widgets. Having this helps distinguish if a file was dropped or if the user simply typed something in the QLineEdit.
Adding missing Q_PROPERTY for some of the filter parameters.
