I know that I can store metadata in the file itself (or in an XMP sidecar file) by pressing Cmd/Ctrl+S. Or by choosing Metadata -> Store Metadata in File from the menu.
I wonder why I need to choose this manually. I did not find any way to set this as a default. Compared to Bridge or pretty much any other metadata-oriented tool, this seems like a disadvantage. I know that the data gets stored in the catalogue, but I'd rather have it in the files as well!
Am I overlooking something? Can I set Lightroom up in a way that does this automatically?
