YouTube Leanback - Enhanced Userscript

This userscript enhances the YouTube Leanback app (primarily for smart TVs and devices) by providing full control over various features such as disabling ads, enabling background playback, and customizing user agent strings. It also enables seamless remote control functionality, allowing you to easily cast content from your phone or other devices to your TV.

Features

• Background Playback: Keep videos playing even when the browser tab is not in focus.

• Custom User-Agent String: Modify the user agent string to simulate a console (e.g., Xbox Series X) to unlock features or avoid device restrictions.
• Remote Control: Easily control the YouTube Leanback app from your phone or another device.
• Profile Switching: Switch between multiple profiles easily without syncing with Google Chrome accounts.
• UPnP Multicast Support: Cast content from one device to another seamlessly across your network.
