Lightweight Spotify Extension for Paralegals and Lawyers: Zero Polling
An observer-based design that leaves your CPU alone.
💡 Overview
Anything running in the background should be nearly invisible. Long documents, precedents and exact wording demand quiet 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.
