A look at the new TweetDeck.

TweetDeck, the popular Twitter application for power users, has been updated with a completely new design for Mac users.

Twitter, which owns TweetDeck, revealed the changes on Friday. Version 3.0.2 of the software comes with the same column-based design users are accustomed to, but adds a new sidebar on the left for more quickly navigating across columns. The new version also includes drag-and-drop rearrangement for columns and the ability to translate tweets.

TweetDeck for Mac also includes improved filtering for mentions, retweets, and other features.

The new and improved TweetDeck is available now in Apple's Mac App Store. It's available for free.
