So you want to learn electronics? I suggest that you take the time to actually learn the theory behind it and learn how resistance, capacitance, inductance affects the system. It is hard but helps a lot. If you want to understand digital systems, then learn how digital basic components work and how you combine them to create more complex systems. Had electronics as my major in my bachelor's degree, and the mental model is really important when it comes to electronics, and the only way to really understand it and get the correct mental model is by repeatedly analyzing the networks and the change over time (resistance,capacitance,inductance) and all of sudden it makes perfectly sense!
Funny thing, I did the same thing (used Jellyfin for several years, then Navidrome for probably a year) and now moved back to Spotify. I think the discovery of music in self-hosted apps is worse. I like to listen albums mostly but I always happened to listen to the same handful of albums, only because those were the first on my mind. I think Navidrome's smart playlists have potential though. Did you come up with a good way to rotate the music?
I'm excited to see what's the Batch api going to look like. I have a few projects that definitely need it to make operations atomic.
Also, readonly/hidden fields are a great addition!
