## Description

This is a Chrome browser extension that serves as an HTML5 video speed controller and media playback speed manager. It is designed to adjust the playback rate of video and audio elements across any website and provide a utility for navigating media timelines.

The tool features a dedicated interface for mapping custom keyboard shortcuts to control playback and timeline navigation. It allows for the creation of domain-specific playback rules to set default speeds or disable the controller on specific websites, and it includes a mechanism to persist selected speeds when native players attempt to reset them.

The project covers media timeline navigation via fixed increments and markers, as well as visual customization for the on-screen speed indicator.
