Subline 0.3.1

Subline 0.3.1

Fixed

• YouTube Music: lyrics now follow each song. When YouTube Music plays queued songs back to back, the playback position and length carried over from the previous songs. Synced lyrics were rejected or stopped advancing. Position, seeking and song length now come from YouTube Music's own per-song progress bar (browser extension 0.7.2).

Install

1. Download Subline-0.3.1.zip, unzip, move Subline.app to Applications and open it (Developer ID signed and notarized; macOS 14+, universal).
2. If you loaded the extension manually, reload it after updating (it should show 0.7.2).

subline-extension-0.7.2.zip is the Chrome Web Store upload package (for developers / manual loading).

• Tap a line to seek, per-song sync offset.
• Second line: CJK romanization, or Apple on-device translation (macOS 26).
