We won’t dive fully into the pre-release history, but we’d bet the developers at Briefs LC are excited to see that Briefs ($200) is finally available in the Mac App Store. First submitted for approval in 2010, it can now be downloaded, along with the companion Briefscase app for iPad and iPhone. If you’re looking to mockup apps using a Mac, Briefs offers you a way to do it, complete with an elegant drag and drop interface.
