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)
Option-click to Hide Apps Quickly
This trick has been available in the Mac OS for years, but many people still don't know it. If you have too many windows cluttering up your screen, you can hide specific ones easily as you work. When you're in any application, hold down the Option key and click on another app's window, on the Dock, or in the Finder to switch to that other app and simultaneously hide all the windows in the previously current app.
