Please, please, please ist it possible to add a new option in “Action after Export”? I would be happy with “open the file in Explorer”, in german: “Datei im Explorer öffnen”!
If you don’t mind editing the XML file, then yes it should be possible.
I’m not at a computer right now, I can’t remember the exact filename. But I have made my own in the past. For example a after export option that converts a wav export to MP3, MP4 and FLAC in one go.
