Ambrosia Software has released Snapz Pro X 2.1, making the popular still image and video screen capture utility a universal binary for native performance on Intel-based Macs. Other changes provide generally improved performance, support for QuickTime compression sessions, compatibility with the Mac OS X 10.5 Leopard beta from WWDC, the (restored) capability to use "Save Later" when post-processing movie captures, and various bug fixes. The update is free to registered users; it's an 11.8 MB download. New copies of Snapz Pro X cost $30 for still image capture only, or $70 if you want to add movie capture capabilities.
Two Shortcuts for App Exposé
If you want to see all the windows for a particular app via App Exposé, there are two hidden shortcuts. For either, start by pressing Command-Tab to bring up the app switcher. Then, while still holding down the Command key, press either the 1 key or the up arrow. That puts you into App Expose mode, with all of an app's windows showing, and recent documents in a row across the bottom of the screen. Let up on the Command key, and then you can press Tab to cycle through all the running apps.
