It's like Night Shift on... steroids!

When using this application, it appears to be impossible to tell which screen is which. When I have a laptop and two external displays connected, the application lists "Screen 1", "Screen 2", and "Screen 3", but there is no way to determine which screen corresponds with each number. If I select only two of the screens and apply an effect, the effect is applied to all three screens. How do I apply effects to only one or two screens without affecting all three screens???

**Disclaimer**: I've used Black Light (the forerunner to this product!) for years now. #Pro It's stayed functional when others have broken during major OS changes. It can handle multiple displays and even plays nice with Magnet for Mac. Please believe, not every MacOS application does. I can click "please invert, apply this color" and not have to worry about funny keybindings (i.e., NegativeScreen) #Con It's disappointing that it still doesn't have a simple 'monochrome' option like the now-discontinued Blacktree Nocturne. I don't necessarily want all my colors inverted; I want BLACK and WHITE. Sometimes BLACK and WHITE with a red filter. As it stands, only the latter's possible in Black Light - in fact, as featured in many product screenshots. Good for late-night work, but not great when you want something monochromatic or in a particular color (think purple-on-black for Truman State "Spirit Fridays.") #Take-Away: The new "night-timer" is a lovely addition. I'll support a simple app that doesn't die when climbing High Sierra. I'd still recommend it with more enthusiasm given explicit monochrome (this-color-white, this-color-black).
