Maybe I can add one suggestion :

In the Preprocess panel, after running a filter, sometimes for any reason, the user needs to STOP running the filter. It would be nice designing a "STOP" button in the Preprocess panel similar to the existing one in, e.g., Classify panel.

Not quite sure what you mean. The Remove button will just remove the selected attributes. The Undo button will un-apply the last filtering operation that was performed. The problem with setting the filter to None is that complex configuration settings would potentially be lost. I usually apply a filter, discover that I haven't quite configured it right, and then hit Undo to change the configuration of the filter.

That’s a good suggestion and we’d love to do that but it would require refactoring an enormous amount of code. Command-line option handling has always been separate from configuration in the GUIs. The two have only recently been unified to some extent.
