made an account just to add to this thread so the people who make flux might someday do this: just make it off by default. i love flux and i'm still glad i got it, but this "backwards alarm clock" thing is genuinely confusing, i scanned the options menu 3 separate times, thinking i must be missing something, before googling it and finding this thread, and realizing i did miss it because i had no idea what the phrase "backwards alarm clock" meant. you can and should rename it something less confusing too, but even if you keep calling it that, just have it off by default because no one wants it. no one installs flux to have a backwards alarm clock, they just want their screen dimmed, so that's all flux should do BY DEFAULT.
again, i still like flux and will still recommend it to people but i hate that now i have to say "hey go get this cool app btw when you get it you have to open the options menu and disable these popup notifications to make the app usable so it doesn't pop up every 30 minutes while you're playing a game or worse, doing work"
edit: and the fact that this is a 5 year old thread and this is still a thing is actually kinda impressive. i dunno how you go that long without doing any kind of focus testing because you'd immediately find out that probably 90% of people turn it off. or maybe they don't, because they actually can't find the spot to do it?
