I really wish people would stop trying to innovate with user interfaces. In a comment below you criticize this UI because it doesn't have delimited interface elements. I agree that non-delimited user interface is really bad, but I attribute that mostly to Microsoft's flat design innovation, which I didn't like at the time, and I still wish I hadn't had so much influence.

As for invisible scroll bars, again we agree. But I think that was Apple. I'm sure somebody will correct me if it wasn't.
