I love this one. the only thing missing is a hotkey like alt+r for inverting.

100% an absolute must for me. For all of those sites out there that only have a dark mode these days, this is a life saver. Or eye saver. Headache saver. Astigmatism sucks, and dark-mode only websites cause physical pain. This inverter means I don't have to invert my entire OS temporarily to read a website anymore. Thank you Hugh!
