Support for smart mix and option to set by default, tracks view on home and new views on the other pages #96

Hi! I love your work on this app. I think it is really beautiful (especially on Android Auto and Android TV). You have probably thought about this already, but I have a few suggestions to help improve the app:

• First of all: Support for smart mixes, and an option in the settings to set this action as the default when selecting a track. I thought about this because I use the AudioMuse plugin ([Here](https://github.com/NeptuneHub/AudioMuse-AI-NV-plugin)). It would be awesome!
• Second: Support for a track view on the home screen, similar to YouTube Music and Spotify. This would be the perfect scenario for smart mixes (in an album, it makes sense to listen to all the songs, but not in a quick pick section).
• Lastly, it would also be great if each view in the app (albums, artists, songs...) had its own section, separated from the other elements.

Those are my ideas! I just wanted to tell you that I'm really excited about this app; it's one of the best for Navidrome. I would love to help out if you need it (I have at least tried translating it into Spanish), though sadly I don't have any programming experience in Kotlin or Android apps.

Greetings from Spain!
