Add Playlist Folder Support to iOS App #116
Description
The Koel iOS app (version 2.2.3) currently doesn't support playlist folder organization, a feature that's available in the web UI. Right now, all playlists appear as a flat list with no hierarchy.
For me, one of the standout features of the Koel web interface is the ability to organize playlists into folders. This makes managing large music libraries so much easier. No other self-hosted music service has this feature (likely because many rely on integration with existing third-party mobile apps). Koel has its own player app, making this a unique possibility.
I'd be very excited to see this feature added.
