Twitter introduces three new features and kills off three others

Out with the old, in with the new. Twitter's main account has just introduced three new features (night-time mode, real-time updates and updated compose box) while @TwitterSupport bears bad news for fans of Twitter's TV apps. 

Twitter's three new features may already be familiar to users with the iOS or Android Twitter app but they may come in handy for those using mobile.twitter.com, Twitter Lite or Twitter for Windows.
