Excellent little app.
Tried many different screen dimmer/shader apps before. Most other apps had missing features or didn't work at all with my current setup (Mac Pro with multiple displays).
+ low CPU/RAM usage
+ works great with multiple displays
+ works flawlessly with f.lux App enabled!!! (No flickering, blinking, whatsoever!)
+ user-configurable keyboard shortcuts (important to me, i use many custom keyboard shortcuts!)
+ works with macOS Sierra (tested w/ 10.12.1)
