I love Roon first. There are two things which would make it more enjoyable for me:
Add a “General Settings” entry to regulate the time the opening quotes appear (I hate not being able to finish it before it disappears)
Add an option for recommendations to be sourced only from my library.
I know a lot of people use a streaming service, I do too. I also have a large library and sometimes I forget what’s in there.
Recommendations central to my library. I use Tidal but have a large library too. Sometimes I want to re-listen to my stuff so I can load it to portable sources.
