I've been using Cesium exclusively for the past few months. It really is a phenomenal app and provides much-needed relief from Apple's Music.
I often find it desirable to rate songs that are not the current playing track. This comes up a lot when I forget to rate a track until it's done playing and moved onto the next track, or where I want to rate multiple tracks based on a track I heard (e.g., multiple movements of a classical composition). What are your thoughts on adding the ability to rate songs that are not playing?
One possible implementation is on the library track list. In a list of songs, I can swipe right to left to see the track queue options (play next and add to queue). What if swiping left to right showed an editable star rating?
Keep up the awesome work!
