TweetDeck for web and Chrome gets New Tweet panel with image previews, autocompletion

TweetDeck just received a big upgrade for those who compose as many tweets as they read. Updated versions of TweetDeck's web and Chrome apps now include a simple, dedicated New Tweet panel that shows image previews and streamlines posting to multiple accounts. It should also be much faster -- the new client suggests usernames and hashtags as you type, speeds up replying to multiple tweets and automatically shortens web addresses. While only browser-based users will see the New Tweet pane today, Twitter promises corresponding updates to TweetDeck's native Mac and Windows apps in the near future.
