We’re currently testing a new version of TweetDeck with a limited number of people. This preview of an improved version of TweetDeck offers enhanced functionality and incorporates more of what you see on twitter.com. People participating in the TweetDeck Preview can expect to see features like a full Tweet Composer, advanced search features, and new column types. We’re also introducing Decks—a new way to group columns into clean workspaces.
Note: If you need help with the current version of TweetDeck, you’ll find FAQs and other help articles under the website and app integrations section of our Using Twitter index.
