I like the interface and the team projects. It's clean. Commonly used elements are always in view, which I really like.

Once you have a firm handle on how the program works, everything is extremely straight forward and intuitive. Also, the icons that comes with the program look professional--less bubbly and round like some other products have.

Love how easy it is to create complex, interactive prototypes to help showcase new features and functionality that we want to implement without spending the money to have development code our potentially throw away designs. Love the ability to share designs online with Axshare Love, love, love the community - the only way to find solutions to problems and better ways of producing effects in my prototypes.
