Smile has updated both PDFpen and PDFpenPro to version 5.8.5 to add compatibility with OS X 10.8 Mountain Lion. Additionally, both releases fix an issue with scanning when running 10.7 Lion, as well as an issue where resampling at a lower resolution produced a larger saved file. Both updates are rounded out by other unnamed minor fixes and improvements. ($59.95/$99.95 new with a 20-percent discount for TidBITS members, free update, 40.7/41 MB)
Two Shortcuts for App Exposé
If you want to see all the windows for a particular app via App Exposé, there are two hidden shortcuts. For either, start by pressing Command-Tab to bring up the app switcher. Then, while still holding down the Command key, press either the 1 key or the up arrow. That puts you into App Expose mode, with all of an app's windows showing, and recent documents in a row across the bottom of the screen. Let up on the Command key, and then you can press Tab to cycle through all the running apps.
