I may not have your flow quite right, but I tried it out.
I...
- enabled the file-remover,
- loaded some to-be-auditioned files into the playlist, and then
- used Next or Alt+Next to filter the playlist such that it contains a list of the files to remove. Then
- Selected All, and used REM...Remove...Physically Remove.
Building the inverse playlist is not quite intuitive but I agree it seems like you are right that it is better than a mix of winamp + explorer/cli work. Thanks for the tip
