With a focus on improving compatibility with the MacBook Pro with Retina Display, Global Delight has released Voila 3.3, addressing a number of bugs specific to Retina display screenshots in the screen capture utility. Also fixed are crashes related to multiple monitor setups and a video corruption problem on the MacBook Air. For those with the MacBook Pro with Retina Display, note that you can set different export formats in Voila’s Export preferences; that way you can easily export more-compact formats when the Retina display screenshots are too large for email or a blog post.

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.
