Twitter has updated the TweetDeck Mac app. The update includes a redesigned sidebar on the left for easier navigation across columns. The new TweetDeck Mac app also has drag-and-drop rearrangement of columns in the sidebar, tweet translation, filter interactions (mentions, retweets, favorites, followers, and lists). You can also filter search columns by engagement (minimum number of retweets, favorites, and replies). You can download the free TweetDeck app from the Mac App Store now.
