It has been some time since its last update, but Panic has now released Transmit 4.1.8 with a modicum of fixes and improvements for the file transfer software. The update fixes a kernel panic that occurred with Transmit Disk when using OS X 10.8 Mountain Lion as well as a possible crash when viewing a mount point folder after unmounting a drive. It also adds support for Growl 1.3, improves compatibility with AS/400 and Personal FTP Server Pro, and updates the item count when filtering in the list view file browser. Other fixes address an issue with double contextual menus and miscellaneous display issues. A quick 4.1.9 update fixes a possible issue with the Transmit Disk menu extra, addresses a keychain issue in 10.6 Snow Leopard, and improves Growl compatibility again.

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.
