Cocoatech has released Path Finder 5.7.6; this minor update to the company’s Finder-replacing file browser corrects several issues related to Mac OS X 10.7 Lion, such as improving compatibility with non-HFS volumes and authorized file operations, removing the AirDrop item from Path Finder’s sidebar, and eliminating duplicate entries in the permission pop-up menus.

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.
