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)
File Email with a Key in Apple Mail
In Mac OS X 10.4 Tiger or later, you can use the simple and fun MsgFiler Mail plug-in to file Mail messages using keyboard shortcuts.
New in Apple Mail 4 (the 10.6 Snow Leopard version), to assign a keyboard shortcut to any mailbox on the Move To or Copy To submenu, you can also open the Keyboard pane of System Preferences, click Keyboard Shortcuts, and select Application Shortcuts in the list on the left. Click the + button, choose Mail from the Application pop-up menu, type the name of the mailbox in the Menu Title field, click in the Keyboard Shortcut field, and press the keystroke combination you want to use. Then click Add.
