WAV/AIFF: library scan, quality probe, native tag read/write via embedded ID3 chunk (RIFF id3 / AIFF ID3), cover art, ReadFileMetadata, ExtractLyrics, and FLAC<->WAV/AIFF conversion (PCM, bit-depth preserved via ffprobe). Treat WAV/AIFF as lossless across all convert sheets (no bitrate picker, Lossless labels) via isLosslessConversionTarget. Native MIME maps for SAF. Redesign the track metadata three-dot menu to a settings-style grouped card with a single divider above Share.
LyricsPlus (KPOE): word-by-word synced lyrics with multi-server failover, converted to enhanced LRC. ReplayGain: standalone EBU R128 (re)scan writing REPLAYGAIN_TRACK_* tags via native writers or FFmpeg, with batch action in queue/album screens and SAF support.
