Extension Features

Highly capable and easy to use. Featuring intuitive interface and a few highly performant, but powerful features.

Blazingly fast

The internal logic that manipulates the video is written in plain JavaScript, has a tiny footprint and is blazingly fast.

Limitless platforms

Not limited to any specific video streaming platform. Aims to work everywhere, including embeddable videos.

Minimal interface

Thoughtful design that doesn't get in your way, but provides you with all the necessary options to get the experience you deserve.

Adaptive appearance

Automatically applies the appearance that you have set as personal system preference. If your system is in light or dark mode, the extension will be too.

Cross-browser

Single source of truth, available for all major browsers and tested on Chrome & Firefox. It works in all Chromium based browsers as well.

Magic touch

Toggle between modes with built-in pinch inwards/outwards functionality. It is working on touch screens, trackpads with multi-touch gesture support and also with a mouse-wheel in combination of holding CTRL key on your keyboard.

Internationalization

Supports handful of languages, but aiming to support all major languages with the help of the community.

Keyboard shortcuts

Customizable within the browser built-in interface, rather than extension's interface, to avoid conflicts with other extensions.

One of those extensions that you forget you even have installed, because it really should just be how things work. Then you go to another browser and enter Letterbox Hell™️ before remembering how dang useful it is.

Works as expected and solves the annoying fact that Dinsey+ doesn't support ultrawide monitors.

Brilliant, does exactly what it says it'll do and provides a nice UI and shorcut buttons to enable. UPDATE: Can I give you a 6th star since this also works for Xbox Cloud Gaming?!
