This is a really basic feature that Plex has had for years on every mobile app.
I have 1000+ albums, and I think a lot of others are in the same boat. I like to browse and find albums I haven’t listened to in awhile, but manual scrolling takes forever to get through the library. Edge scrolling ala Plex is great, intuitive, and there’s absolutely no reason for roon not to have it. It’s really hard to believe it doesn’t exist in the mobile apps yet, when it’s such a basic feature.
