I've just updated to Mountain Lion and added my twitter account in Settings. Now I've noticed that in the Notification Center options unlike all other apps there, twitter has no checkbox for 'Badge app icon' and 'Play sounds when receiving notifications'. Just the one for the 5 most recent messages. So while the other apps have Badges, Sound, Banners under their name, Twitter just has Banners. Is this normal? The reason for checking that out was that I noticed that upon receiving a Twitter message, no sound was heard, just a notification center message. So I wanted to turn sound on for Twitter in the notification center, but apparently their isn't an option to turn in on. I've seen screenshots with Twitter having Badges, Sound, Banners. So were these options perhaps deleted in Mountain Lion's recent version?
