Lightweight Spotify Extension for Audiobook Listeners: Zero Polling
An observer-based design that leaves your CPU alone.
💡 Overview
Anything running in the background should be nearly invisible. Spoken word benefits from speed control more than music does.
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.

Spoken word benefits from speed control more than music does.
The problem: Fiddling with tabs to change speed is annoying.
The fix: Use the speed control from 0.5x to 2.0x in the popup.
