Feature Request: Add animated volume level visualization & offer to help translate to Chinese

[aunight]

Hi, thanks for this awesome project!

I have two suggestions:

1. Animated volume level indicator
   It would be great if the extension could display a dynamic animation (such as a moving bar or waveform) to visually indicate the current volume level while adjusting.
   Ideally, this can work similarly to how the native Windows volume overlay or the app EarTrumpet shows volume — with a responsive visual feedback bar that reflects the volume percentage in real time.

2. Chinese translation support
   I’d love to contribute a Traditional Chinese translation (or Simplified, if preferred). Let me know if you're open to localization, and what your preferred method would be (e.g. language files, Crowdin, etc.).

Thanks again for your great work — excited to see where this project goes!
