As detailed here: How to scroll through 500 artists? Browse by folder, or by Artist index (ST - Santana)?
the current version of Roon remote for Android phones makes it almost impossible to browse through very long lists. The PC and tablet apps have:
- a “Focus” feature, and
- a scroll bar at the bottom of the Artists screen, which displays the first X letters
These features, or something else which makes it efficient to browse through long lists, should be introduced to the Android phone version of the app. Until they are, unfortunately I cannot buy a licence, as browsing my collection would be practically impossible.
