Over the past few months, Twitter has added a load of useful features to TweetDeck on the web, leaving the desktop app to age. Well, the Mac version of the 140-character social network software is finally getting some of those tools. With an update today, TweetDeck for Mac handles the newfangled shared account option for groups and allows for DMs (and using them to share tweets) with more than one person. You can also add up to four images per tweet and both GIFs and video footage plays in-line from any column. All of these features have been live on the web already, but it's nice to see the folks at Twitter giving some overdue attention to the desktop software. If you haven't already been alerted to the new version, nab it from the Mac App Store right here.
