In this concept, there's transparency, to add depth, vitality, and efficiency.

In applications that require your attention, the UI gets out of the way, but when you need to see what you're doing with your content, you can easily know what to click on.

As a plus, all of the icons have been redesigned, and there's a brand-new palette of colors.
