Twitter bought TweetDeck, last year and December saw the first vestige of TweetDeck branded by Twitter. Users were not entirely happy with this update, as it deleted many useful and popular functions that TweetDeck had. Twitter has now updated TweetDeck to include some of these missing functions. The updates also seem to make TweetDeck an extension of Twitter for web. According to a blog post on Twitter, for one, you can now edit and delete lists right from within the app. Also, all user profiles come with an "Add or Remove from Lists" menu item. List memberships should now be easier to manage.
TweetDeck gets updated with inline media
Furthermore, Twitter has added two more columns to TweetDeck, which will allow you to see additional activity on Twitter, including retweets, favourites and follows. An Interactions column is listed under the "Add Column" tab, which functions a little more like a mention column. In fact, it functions like the @username column on Twitter for web. It shows when you've been mentioned, retweeted, favourited and followed. Another column they added is the Activity column. Here, the activity of everyone you follow will be listed. You will be able to see follows, retweets and favourites that people you follow have done. This is much like the Activity tab in Twitter for web.
TweetDeck now also has in-line media previews, so images and videos can be viewed more quickly. A small preview of the image or video will be seen under the related tweet. However, if you don't want to want to see in-line media, you can turn the feature off in Settings>General. Additionally, you can view a large preview of images and videos in an in-app media gallery. Click the preview image, or the URL in the Tweet, and the media will be displayed in a large gallery view.
Finally, the Edit and RT feature is back in the form of an Edit & RT button. Previously, you would only be able to RT using "quotes", which didn't let you edit Retweets before sending. To download and update the app on Windows, close the app and restart. The app should auto update. TweetDeck for Mac can be updated through the Mac App Store. For Chrome users, restart the browser and the app should auto update. Finally for web, Go to web.tweetdeck.com and hit your browser refresh button.
