Custom Ringtones And Notifications!

It's been posted many times but it should become a feature. Add more ringtones! Maybe have like 5 defults and let nitro users upload a custom 10 second audio clip as a ringtone. Also you could have more notification sounds, maybe 3 defult and nitro get a 2 second custom. Also maybe a little more control on notifications, maybe a favorite friends option which will allow you to only get notified by the friends you pick when DMed.
