I would like to be able to filter search results by format (e.g. Flac, no-mp3, etc.), without having to resort to the (fantastic) focus feature. It would be great to have a much simpler search results filter for format.
Similarly, I would love to be able to define format related constraints for roon radio. I have a large library with a lot of MP3, but typically I only want to listen to lossless when listening to roon radio.
2 could be achieved by optionally constraining the radio for focus results, though I suppose an easier implementation would be as a simple constraint parameter in the radio settings.
