Twitter's iOS app gets cool new features (pictures)

The newest version of Twitter for iOS comes with new options for posting videos and private group conversations, but is slow to roll out to all users.

As always, you can stay up-to-date with people you follow in the Home feed.

Touch on an individual tweet to get an expanded window with more info.

Check your notifications screen to see people who have followed you and replies to your tweets.

The Me section of the app shows your short bio, your latest tweets, and you can use tabs at the top to switch to all your tweeted photos and favorite posts.

With new features that are slowly rolling out to all users, Twitter will let you shoot and post videos to your timeline. Just like in Vine, you can touch to record multiple clips and let go to stop.

With new Group conversations, you can select up to 20 people with whom you can have a private conversation that doesn't show up in any other feed.
