Firstly great job on Roon so far. A couple of things to consider please.
An option to play the highest quality version of a file available. If Tidal or Qobuz subscriber it would be cool to play the Tidal version of songs in your library. Perhaps a switch in settings for Prefer Tidal or something.
Roon Radio gets stuck in a genre. ie start an 80s song and all you will hear from Roon Radio is more 80s stuff. Whilst OK this hardly discovers new music. The selections within a genre are generally pretty good.
