Shady for Mac — Pull a virtual shade over your screen, rest your eyes

"A poor man's f.lux" is a good way to describe Shady. A hotkeyable screen brightness preset might be useful to some, but I prefer the greater capability of f.lux if you want to manage screen glare.

I use this frequently — it's a terrible app that's pretty useful. It doesn't support Retina screens very well, doesn't work on secondary displays/full screen apps, and hides every time you open something like Mission Control, flashing the bright screen into your eyes. It can be useful though.

I feel like I've seen this done a few times before. Anything that particularly sets you apart from the others?
