This theme is based on Nexus 6's default theme, Google Now Launcher, The simplest launcher as far as I can see.
However, Nexus 6's default icon size, text size and text font are not my favorites. So This theme changed the font style, added customizable options to icon sizes, icon text sizes, icon text colors, add corner to icons, background alpha, search box visibility.
One of the simplest and most productive themes on the market.
Least Memory, most powerful.
