Twitter has rolled out updates on the desktop edition of TweetDeck.
Twitter highlighted the updates:
Now your columns are arranged in one continuous horizontal row, allowing you to navigate smoothly left and right with the scrollbar.
Manage your columns
With the addition of the new Columns button it’s now easier to arrange your columns. With the column drop-down open, simply hover over the “drag” icon to the right of the column name you wish to move, click and drag the column to its new position, then drop.
Act on what’s happening
A menu icon on every Tweet gives you instant access to more Tweet actions, like “Create link”, and user-related actions, like “Block”. This makes it possible report a user for spam, add an account to a list, delete your own Tweet, and much more, all without having to leave your main column view.
This updated version is already available on the web edition optimized for Chrome browser. Windows app is also updated. Updated OS X app would soon be available through the Mac App Store.
