Back in May I reviewed the first version of Carousel, a beautiful Instagram client for Mac that, thanks to the Chameleon framework built by The Iconfactory, brought Instagram’s photo streams and profiles to the desktop with a gorgeous iOS-like user interface. Whilst in the past month, with Lion nearing its final release and the WWDC, we’ve seen several examples of iOS apps making the big leap to the Mac, Carousel was one of the first apps to try the iPhone-inspired approach with a vertical layout, tabs, and popover menus. Together with Twitterrific, Carousel is a fine example of iOS interface schemes coexisting with more standard Mac applications.

Carousel 1.1, released today, adds a number of new features and refinements to make the Instagram experience on OS X even more beautiful and easy to use. First off, search: you can now search for specific @users or #keywords on Instagram, pin your searches as you would in Twitter for Mac, or click on tags and usernames in photo comments, which now are better styled to indicate the original author’s caption. Saved searches sit below the search bar, but to perform a search you’ll have to choose an element from a popover menu. The app has gained a new “likes” tab to see all the photos you’ve liked and a fetch separator to start where you left off in the stream, but more importantly gestures are now supported to easily open a photo in Quick Look (pinch and zoom) or check out a profile (swipe on the photo). It feels very natural and smooth using a Magic Trackpad.

Among the little fixes and refinements, the developers have updated the iOS-like toolbar to make sure the selector is draggable (try it, neat animation in there) and the comment form remains visible even if you click outside of Carousel’s main window.

Carousel 1.1 is a solid update for the most beautiful and intuitive Instagram client currently available on the Mac. You can buy Carousel at $4.99 on the Mac App Store.
