+
+## Scripts
+
+### 1. Better Share Button (`better-share-button.os.js`)
+
+Clicking **Share** instantly copies a clean video link to your clipboard: no share dialog, no `?si=` tracking token.
+
+#### Features
+- **One Click Copy:** Share skips the dialog and copies the link straight away, with a small confirmation toast.
+- **Tracking Stripped:** Copies `https://youtu.be/<id>` instead of `https://youtu.be/<id>?si=...`.
+- **Shorts Support:** The Shorts share button copies `https://youtube.com/shorts/<id>`.
+- **Player Buttons Too:** Covers the watch page, the fullscreen player actions, and the player share button.
+- **Dialog Fallback:** If the native share dialog still opens, its **Copy** button copies the link without tracking parameters (keeps `t` and `list`).
+- **Language Independent:** Targets the share icon rather than the localized `Share` label.
+
