Usability:
If ever there was a thing that attracts me the most in Mac software, it's clean UI design and usability.
It's this thought-out approach that a lot of Mac devs have on their software. It's often the little intrinsic details that get me excited about an app. You actually 'want' to start working with it just for the sheer fun of it.
This weeks app is no different. Except,... I also need to work with it instead of just 'wanting' to work with it.
