Noodlesoft has released version 3.0.9 of its file cleanup utility Hazel, which updates some icons and fixes some issues when viewing the app with the new MacBook Pro with Retina Display, as well as adding a Developer ID that allows the app to be installed without difficulty when using OS X 10.8 Mountain Lion’s Gatekeeper security feature. Hazel 3.0.9 also displays more-accurate error reporting in its preview, prevents a whole pattern getting deleted when you delete a custom token, and fixes an issue with the incomplete downloads setting that was causing prediction errors. ($25 new, free update from version 3.x, $10 upgrade from previous version, 5.2 MB, release notes)
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.
