TweetDeck for Mac updated with sidebar-focused design

Twitter just recently spruced up the Windows version of TweetDeck with the web edition's simplified, sidebar-driven look; it's now the Mac app's turn. TweetDeck 3.0.2 on OS X brings virtually the same interface as its Windows counterpart, including drag-and-drop columns and the ability to filter searches by engagement. If you take your social networking extra seriously, the 3.0.2 update is waiting at the Mac App Store.
