I've used f.lux for years and I really like it, as I have noticed my sleep patterns have improved during that time. However, I do think that the transition is sometimes really too quick. I can be working away, deep in 'flow' and I will alarmingly perceive the screen going darker/changing a couple of times over the evening. It almost feel like I am passing out or getting a precursor to a migraine sometimes, with the change, which is quite jarring. The other thing is the constant annoying notifications of "You are going to be awake in 'x' hours". Well, actually, no - If I am up and coding until 2am, then chances of me being awake at 6am when you expect me to is just not on. I also wish they would have an 'emergency awake' function, so that when I jump on to the keyboard to fix a server outage at 5am after many hours away sleeping, that it would immediately go to full brightness there and then, rather than wait until 0630 as per normal. If I am active at that time after a long break, I am NOT going back to sleep and I have to have full illumination of all those red signals on my server dashboard! :)

I'm not sure which OS you're on, or how old a version, but on MacOS it should be on slow transition by default, and I'm not really sure of the details on "fast transition". On Windows it actually has a more verbose option saying to transition over 60 minutes. I'm wondering if that's the default, not-Fast-transitions on MacOS?

  Ok, Thanks, I just checked the preferences, and I noticed that 'fast transitions' was check ON, which is probably what is happening. I will test it out over the next few days and see how it goes - though I just got the update notification for 10.12.4 with Night Shift (I am currently on 10.12.3) so I am torn between trying that out instead.

there is a setting in the menu bar: Disable: > For an hour > Until Sunrise > For current app

  Thanks - yeah that is normally what I do, but sometimes in the rush I just want to start opening up diagnostic apps and don't really realise until a bit later when I find myself squinting and straining my eyes to read a really dark screen in (what is now) a brightly lit room. It would be nice if f-lux could detect that there is activity after many hours away, and the ambient light in the room is quite high, so let's go "throttles to the firewall" automatically and set the screen back to daylight mode to commence the work day earlier than normal.

  I definitely wish there was a keyboard shortcut for this. Especially since I constantly have to turn f.lux on and off because it's not compatible with full-screen YouTube/Vimeo/etc.

you're not crazy. for certain versions of osx, it's "just broken". i've seen it with my own eyes, and personally flux has only worked for me very well recently (like in the past 6 months). i advise you tell the developer!

You can disable those 'You are going to be awake in...' notifications. On Mac, it's Options > Backwards alarm clock
