This extension should have WAY MORE positive reviews. It worked when nothing else did. I tweaked everything in the Win11 settings to prevent screen lock when I was away from the laptop, but nothing worked. There's probably some hidden config bound to my camera that makes the laptop lock itself when I am not facing it. This extension solved it. No more failed downloads for me! Thanks!!!!!!!!!

Love the extension. There's just a minor issue with the UI if the dev wants to improve it. So, when I put my Win10 laptop to "hibernate" without turning Sleepless in System off, after turning the laptop back on, the extension's UI stays "red" (as in it shows that it is "on") although it is actually turned off. It's not a big problem, but the first time this happened, you could say I was a bit confused.
