v1.0 with GUI and more
I've used another fork with nice changes, started from there. Added GUI and Settings. Icon for app, menu in Status Bar. Control brightness with slider in the menu. And more..
Also, I've added personal option: control Color Temp aka Night Shift, be default its' disabled in the menu. Using F3 and F4 or slider in menu you can change color temp. I'm personally using it along with brightness.


I don't know how to implement multi monitor option, so it's just enabled. But I hope someone can help me with this.. also, I have only 1 monitor, so I can't test this.
@Bensge Are you interested in this? Also, maybe you can add me as contributor? I would love to help, improve GUI and any other things I can.
@Bensge Hello :) ?
This looks great! Seems like with at least Mojave you can adjust the color temperature of the monitor in the Display settings.
Great work !
