"It lets you control the brightness, Color temperature of the display and RGB as well".
If you decide to try it be sure use the "sudo apt-get install brightness-controller brightness-controller-simple' command instead of 'sudo apt-get install brightness-controller-simple' that they give to get the color temperature/RGB controls.
Please post suggestions for improvement of Cinnamon here
