Photo-editing app Acorn has been updated to version 3.5, and with that update comes plenty of new features to check out. The Magic Wand tool has been updated with the ability to do contiguous or non-contiguous selections, you can now export just a single layer out of the app, there are some new plugin APIs to use and there are of course a whole host of other updates and bugfixes, all available on the official website.
In short, a great app has been made even better. You can nab Acorn over on the Mac App Store -- it's US$49.99. If you already own the app, the update is free.
