In the massive iCloud-related set of software updates, Apple released iPhoto ’11 9.2. Along with providing compatibility with iCloud’s Photo Stream feature, iPhoto 9.2 adds left and right swipe gestures for navigating between photos in Magnify (1-up) view, displays previously imported photos in a separate section of the Import window, and enables you to choose book/calendar/card themes from a pop-up menu in the carousel view. Several bugs have also been fixed, including one that could cause pages of books to print incorrectly and another that could lose saved slideshows and books when rebuilding a library. It’s easiest to get iPhoto 9.2 via Software Update or the Mac App Store. ($14.99 new from the Mac App Store, free update, 357.18 MB)
Compare More Easily in Apple Mail
In Apple Mail, if you need to work back and forth between two different views of Mail's mailbox contents, you can do so quite easily. For example, you might want to look at a mailbox holding all filtered-in sales orders from the past week while also looking at a smart mailbox showing unanswered customer questions.
To avoid constantly clicking between mailbox views and losing your context each time, choose File > New Viewer window to get a second window and then arrange each window as desired.
