Twitter has released TweetDeck 2.1, an update that adds a smattering of features to the company’s column-based client. The new release adds support for photo and player cards (the latter of which can play video and audio), plus it enables you to edit and refine search columns using the new column options (click the magnifying glass icon at the top of a column). It also adds the capability to type “n” to start a new tweet and press Command-Enter to send a tweet. Also included are fixes for Retina display support and profiles that didn’t load under certain circumstances. (Free, 1.4 MB)
