"Picture in Picture with controls" is a Chrome extension by SWZ that enhances your video watching experience. It keeps your video playing in a floating window on top of other tabs, allowing you to multitask effortlessly. The extension offers convenient features like fast forward, rewind, and adjustable playback speeds, giving you full control over your viewing experience.

To use the extension, simply click the Google extension icon, adjust your Picture in Picture settings, and hit the 'play' button. Users can customize playback speeds within a range of 0.25 to 4.0, ensuring smooth video playback. Despite the icons in the Picture in Picture window not being intuitive, the developer explains that this choice was due to limitations with the mediaSession API.
