The “By this Artist” could stand improvement. I infer that Roon takes the first Artist on the main album and displays the albums for him/her/it. If the first Artist has no albums, it goes to the next Artist as its search criteria.
Okay, well and good. But this implicitly assumes that the first Artist is the most meaningful or important. Second or third artists don’t matter for this feature.
I have a better way. Create a drop-down list that contains every Artist of that album AND its Composer, if present. Much more useful and powerful.
