Apple has released Final Cut Pro X 10.0.4, a minor update to the professional video editor with a grab bag of tweaks and fixes. The release improves both responsiveness and quality of broadcast monitoring when using compatible third-party PCIe and Thunderbolt I/O devices as well as multicam syncing and editing. Fixes include a problem with superimposing a video over a background with an alpha channel that would render differently before and after in the Viewer, plus an issue with re-rendering titles after application launch. The update also adds a sharing option for 1080p video on compatible iOS devices, includes multicam metadata in XML project export, and assigns stereo as the default audio channel setting for new projects.

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.
