Levels Tab Volume Control

Levels gives you individual volume control for every browser tab - like a mixing desk for your browser. Set the volume and forget about it, the next time you load the site it will remember.

FEATURES:
- Per-tab volume sliders (0-100%)
- Mute/unmute individual tabs with one click
- Volume boost up to 1000% for quiet audio
- Automatic per-site volume presets (YouTube always at 50%, Spotify at 80%)
- Settings persist across page refreshes
- Dark and light theme support

WHY:
- One tab blasting music while another plays a quiet video? Fix it instantly.
- Want Twitch streams quieter than your Spotify? Set it once, it remembers.
- Audio too quiet on a website? Boost beyond 100%.
- Need to quickly mute a tab without pausing? One click.

HOW IT WORKS:
1. Click the Levels icon in your toolbar
2. See all tabs currently playing audio
3. Drag the slider to adjust volume
4. Click the speaker icon to mute

PERMISSIONS:
- Levels only accesses audio on tabs that are playing sound
- No data is collected or transmitted
- No account required

Perfect for:
- Streamers managing multiple audio sources
- Music listeners who browse simultaneously
- Anyone tired of one tab being too loud

Works with YouTube, Spotify, Twitch, Netflix, SoundCloud, and any website that plays audio.
