Lightweight Spotify Extension for Graduate Students: Zero Polling
An observer-based design that leaves your CPU alone.
💡 Overview
Anything running in the background should be nearly invisible. Months-long writing needs sustained, uninterrupted focus.
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.
