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)
Mac OS X Services in Snow Leopard
Mac OS X Services let one application supply its powers to another; for example, a Grab service helps TextEdit paste a screenshot into a document. Most users either don't know that Services exist, because they're in an obscure hierarchical menu (ApplicationName > Services), or they mostly don't use them because there are so many of them.
Snow Leopard makes it easier for the uninitiated to utilize this feature; only services appropriate to the current context appear. And in addition to the hierarchical menu, services are discoverable as custom contextual menu items - Control-click in a TextEdit document to access the Grab service, for instance.
In addition, the revamped Keyboard preference pane lets you manage services for the first time ever. You can enable and disable them, and even change their keyboard shortcuts.
