Lightweight Spotify Extension for Ultrawide Monitor Users: Zero Polling

💡 Overview

Anything running in the background should be nearly invisible. One wide screen holds many windows, but not an extra music player.

Instead of checking the player every few hundred milliseconds, the extension uses a MutationObserver and updates its UI only when the page changes. The developer describes the footprint as near-zero CPU and memory overhead, which matters if you are already running heavy applications.

🧭 A Day of Ultrawide Monitor Users

One wide screen holds many windows, but not an extra music player.

The problem: Resizing windows to fit music disturbs your layout.

The fix: Use the compact popup rather than another window.

🚀 Try It in Three Steps

1. Open Chrome Task Manager to see what your extensions use.
2. Install the extension and compare over a session.
3. Keep what feels invisible.

✨ What You Get

• Sleep timer: Presets of 15, 30, 45 and 60 minutes with a live countdown that auto-pauses playback.
• Zero-polling design: A MutationObserver updates the UI only when the page changes, keeping CPU and memory use low.
• Shortcut profiles: Standard, one-handed WASD, compact Alt+arrows and function-key presets.

Note: it works with the Spotify Web Player at open.spotify.com only, and does not control the desktop app.
