Updating to version 220.127.116.115, Skype for Mac adds several user interface improvements as well as support for the upcoming release of OS X 10.8 Mountain Lion. The update includes an improved Contacts Monitor (which can be more compactly resized when using other applications), automatic reorientation of mobile video calls when the mobile device switches between landscape and portrait views, the addition of a keyboard shortcut for controlling volume, and an SMS button in the conversation input field. Skype Premium subscribers also get improved screen sharing with the addition of simultaneous video call and screen sharing views. For a complete overview of the improvements, see this Skype Garage blog post for the release notes. (Free, 23.3 MB)
Option-Click AirPort Menu for Network Details
If you hold down the Option key while clicking the AirPort menu in Mac OS X 10.5 Leopard, you'll see not just the names of nearby Wi-Fi networks, but additional details about the selected network. Details include the MAC address of the network, the channel used by the base station, the signal strength (a negative number; the closer to zero it is, the stronger the signal), and the transmit rate in megabits per second showing actual network throughput. If you hover the cursor over the name of a network to which you're not connected, a little yellow pop-up shows the signal strength and type of encryption.
