I'm sure they will add this feature in future as when Roon was created it was for our local files. Now with streaming services added they will definitely enhance it with these features. However till the time this feature is not implemented you can add your favourite album of an artist in your library and then the artist will show up. Yes, roon is not perfect but one of the important feature of Roon is zone creation and ability to play different files for different zones. Also with Roon we can run powerful DSP and stream qobuz or Tidal on our iphone with sound tailored to our need. I always wanted to EQ while streaming from Qobuz in my iphone and Roon has given me that ability. So there are some negetive but good number of positive aspects as well for Roon users. However based on our use case Roon may be hit or a miss.
