  @herf Ah right. Windows apps are kept around pretty differently. I see why this decision was made. Regardless, I think people would still benefit from being able to add an EXE name. Under the right click menu item to disable for a specific time or application, would it be possible to add a button to the list that just says "For an exe..." which would open a file picker when clicked on? Adding a program through this method would add an exception for the full path of the executable instead of the window title. The main window title functionality would stay put and this would just be something used by people who want to add the EXE manually because they know what they're doing.

  Hi team, I suffer from eye-strain which translates to immediate sore eyes for anyone editing photos for more than a few hours. Currently, I use Cxyrus blue light glasses and the fantastic f.lux app to adjust my screen during daily use. The only problem is, when looking to make accurate colours while editing, I have to turn F.lux off which resets the temperature to 6500 and the blue light immediately beams right into my eyes, glasses or not. They literally get sore after five minutes. As I typically use my computer with the colour temperature set to a yellowy 2900 (rather than 6500 which the norm), maybe there's a way I can edit my photos to compensate for the difference in display temperature rather than having to switch between each time? Otherwise, I'm thinking maybe a Matte anti-glare screen protector could help, has anyone had success with this? I'd say this is my biggest trouble with editing photos so any help would be really appreciated.

  f.lux runs on jailbroken iOS devices or on iOS9 with a sideload.

  Hi @BenKlesc - thanks for the post. You are correct about flicker, since most OLED panels today flicker at around 240Hz. I also appreciate the comment about brightness, since this is perhaps the biggest factor that determines how much light people see. However, the information you're posting about blue light is not correct. A few years ago, several companies would pick a range of wavelengths and see how much power was in a particular range, but there is no agreed-upon range like this used in the scientific literature, or in an international standard. Numbers like "6.5% blue light" do not have a "standard" meaning - this is mainly marketing that does not have a physiological basis. That leaves three metrics to consider: s-cone activation, melanopsin activation, and a purported "blue light hazard": Any screen (and especially one with a wide color gamut) can produce intense blue, and this is just a fact about univariance in the cones. So if you are talking about the visual sensation of "blue" there is no difference in which wavelength is used: the s-cones will see this light the same way. On a melanopic level, OLEDs today make about 23% more blue-green light than do LED backlights. So there is no advantage to OLED in this regard. Some people are using the IEC-62471 "blue light hazard" factor, but these hazards are intended for use with extremely bright lights (like lasers) above about 10,000 cd/m2 (more than any screen today), so I think the methodology is improperly used. Still, even on this level, OLED is only about 10-15% lower "hazard factor" - a very small number, since these effects happen over orders of magnitude. If you think there is a blue light hazard due to screens, you'd want to change it by 90% or more (f.lux does). In contrast, most of the filters using this metric today make very minor changes (5-15%). But it's important to say that currently, we think even the use of this metric is inappropriate, given what it was designed to measure, which is extremely high levels of light.

  Might sound a bit rude, but someone has to tell god damn truth. We want to store brightness level (80–90%) for a GOOD reason, not because of some laziness. Reason is PWM flickering (causing headaches by itself, not to say coming along with annoying pitch noise) when (not that modern) display’s built-in brightness is set lower than 100%. Google for details and do reconsider storing brightness as many similar apps already do (Iris, Redshift, Gammy to name a few).
