1.0.6

In this update:

1. Added Automatic Picture-in-Picture (PiP) for YouTube videos (default off)
   • Automatically enables the system’s native PiP mode when playing YouTube videos
   • Videos continue playing in a floating window for a smoother experience, similar to PiP in modern browsers like Arc
   • To confirm the current video, you need to interact with the YouTube page (e.g. click or play) after opening it before this feature takes effect
2. Fixed an issue where subtitles could flicker when adjusting playback using the trackpad
3. Improved app interface and descriptions for a more intuitive experience

3. Improved some interface styles.

1.0.4

This update fixes an issue where subtitles could not be loaded on a browser cold start.

1.0.3

In This Update:

1. Fixed minor bugs and refined UI details.
2. Added an entry point for Picture-in-Picture (PiP): A new icon will appear in the bottom-right controls of the YouTube player. Clicking it lets you toggle Picture-in-Picture. You can also choose to hide this icon in the settings page.

Tips:

1. If YouTube subtitles are enabled, they will also appear in Picture-in-Picture. Changing the subtitle language on YouTube will automatically update the subtitles shown in PiP.
2. After updating, any already-open YouTube tabs need to be refreshed so the extension can correctly detect the subtitles.

1.0.2

Improved device compatibility and video aspect-ratio detection logic.
