The inverted colors of the icon induce retinal after images, and in-app, the whiteout is hard on the eyes The experience on an iPad Air is one of huge expanses of white or badly contrasting off-whitelight blue and stencil-thin pale icons battling the brightness of it all The spartan look works fine on an iPhone, where there is proportionately less white assaulting the eye with the iPad, however, I keep trying to reduce the brightness of the display, but that only further impacts contrast and legibility 
Also why is it not possible to change names of files or folders??
