I agree - at the time I started using Roon in 2015 they advertised it in a kind of nostalgic way, reminding people of how cool the times were when you had big LP’s with nice artwork and texts.
The way to present your library in a magazine-style follows this logic. However, what they can’t? or won’t? be offering is a way to make Roon YOUR personal magazine.
I am reminded of my very first days as a teenage collector, when I met with a much older guy who proudly showed me his gear and LP collection, while pulling out a photo album out of the cupboard, where he had collected pictures and made collages of LP catalog cutouts, together with cut-out reviews for his albums. He would sit in his listening chair and browse through these albums, revisiting memories and getting inspired to put on other records that he owned.
If Roon could do this for me, I think I would be very happy. To enable me to create my own personal magazine, merging 3rd party content with my own collected reviews, artwork and my personal cross-references. I would love that.
