I will definitely get back to you once I revisit the app! I know after one of the early updates addressing music quality I deleted and re-favorited all my files (which took a while) to download them again and the quality hadn't changed. But again, that was one of the early updates. I will let you know if that has changed. There's one feature I wish more frontends would offer but haven't yet, and that's displaying a context menu offering options instead of just playing the song immediately when tapping. Too often I have a nice queue set up and ruin the whole thing by accidentally tapping the song instead of long pressing to play next in queue. Any thoughts on adding something like that?
Also, I wanna give kudos for making it available in the obtainium crowdsourced app configurations page from the jump, that's how I initially discovered your app. It's usually my first stop shop for new apps.
