Unfortunately, this Opera extension is very disappointing. It's supposed to be an audio extension that lets you increase the volume, boost the bass, and adjust the sound for each tab. This sounds very useful, especially for YouTube or music.

However, in practice, it doesn't work reliably at all. Every time you close another tab, the add-on deactivates itself. This is extremely annoying, especially if you have a YouTube tab open and the sound is suddenly reset.

Such a fundamental flaw shouldn't occur, especially with an extension specifically designed for audio and offering features like significantly increased volume or bass boost.

As it stands, it's not enjoyable to use and feels completely unfinished. It would be highly desirable if this problem were finally fixed so that the extension runs stably and reliably.
