It would be great to have the notification shade resemble the stock Android 13 Notification Shade.
The current implementation works, but it doesn't keep up with the latest UI/UX design for notifications/control center. The new versions are much more fun and dynamic. It's a UI paradigm of it's own. The latest stock Android 13 version has better utilization for large screen devices, a better music player, and an overall better separation of the different pieces that make up the notification shade. All the while being more customizable than the current implementation of Samsung's version of notifications.
