It doesn't allow use of digital ink on Mac. I'm quite disappointed in this. In older versions on Windows one could drag and drop PDFs and images. You can't on the Mac version.

The layout is great and it looks and feels like a slick application. If you are doing notes via typing and don't have to insert many images then this will be a great application for you. It beats Circus Ponies in look and feel and is much more intuitive than Circus Ponies. But it is missing two great features and as such I'll be sticking with Circus Ponies.
