Popular Twitter client TweetDeck has been redesigned and rebuilt from scratch to be faster and sleeker. And that’s not all. The older version has been temporarily removed from the iTunes App Store as version 2.0 is supposed to be much more than an upgrade, a replacement app. The older app will resurface once they've updated it to point existing users to the new version.
They call the new TweetDeck a Hollywood-esque “re-imagining” where the soul of the application remains the same but is brought up to speed. It still supports Facebook, MySpace and Twitter but the app’s interface has been revamped. Better graphics, addition of comon gestures for access control like blending timelines, DMs, Mentions, favorites, Facebook News feed into a personalized column, and being resolved for retina-displays are the upgrades worth mentioning. A version modified for iPad is also on its way.
There is much better multiple account handling in this new app. In the Home, Me and Inbox pre-defined columns you can choose exactly which accounts will be used.
The blending of accounts into a column is also very flexible. You can see DMs from one account, blended with your Facebook news feed, plus a couple of Twitter Lists, for instance.
