It truly does look amazing. From your work I've seen you can definitely do a lot of awesome things with it. Though, is it only for MAC? I unfortunately don't have a MAC for design. After researching a bit do you think proto.io would be the better option for a windows user?
EDIT: After looking a I have also found protopie, what do you think of this?
One more edit: I am going to just PM you for further info so I don't spam this thread.
