YouTube Ultrawide Crop by Sudhz

YouTube Ultrawide Crop adds a simple crop button directly inside YouTube's video player controls.

Turn it on once, and YouTube videos stay cropped until you turn it off. The setting persists across videos, refreshes, fullscreen, and normal YouTube navigation.

This is built for ultrawide monitors where videos often show black bars.

Features:
- Adds one button inside YouTube's native player controls
- Toggles ultrawide crop on or off
- Remembers your choice globally for YouTube
- Works across refreshes and YouTube single-page navigation
- Works in fullscreen
- No popup
- No analytics
- No remote code
- No account or login
- No data collection

This extension is not affiliated with YouTube, Google, or Alphabet.
