Volume Mixxer от Rohit Kuinkel

Boost Volume up to 400% ,switch between tabs playing sound from the extension with just one click. It is completely Open-Source and can be found on my GitHub and was created with privacy in mind.

- Use local storage to store and retrieve preferred theme.

Update 1.6.x:
- Introduced a fix to a rare issue where the volume would get very loud on its own
- Added a banner to reflect the current volume status without having to open the extension
- (Tech) Migrated from JS to TS
