Ambrosia Software has released Snapz Pro X 2.3.1, an update to the screenshot utility near and dear to the hearts of authors everywhere. Most notably, the update provides necessary compatibility with Mac OS X Lion (earlier versions didn’t work well in Lion), but there are also improvements to H.264 color management and handling of mono audio devices, along with a few other minor bug fixes.

In Snow Leopard, Option-clicking the Volume icon in the menu bar displays a list of sound input and output devices. Choose one to switch to it; it's much easier than using the Sound preference pane. Also, hold Shift and click the icon to set the system volume, which is separate from the general output volume.
