QR Reader and quick access in main browser screen (manually)

Is it possible that they can integrate a QR reader in the bottom bar?

I have seen that many browsers integrate it, especially the default internet browser that all android have

I have also seen that other browsers allow you to manually add shortcuts to the main browser screen.

I consider that if they integrate the QR reader and quick access to the main browser screen, surely no one will ever use another browser other than Brave
