Focus on Unidentified (Inspector) [Implemented by negating the filter]

I would like to have the ability to choose “Unidentified” as focus under Inspector. It helps to fine-tune my metadata for albums not (yet) identified.

Just toggle identified by clicking on the filter and like all filters it turns into a negative.

Yes. That is easy and it works. Thanks.

Only 30% of my 2000 albums are not identified. Lots of work to go.
