Hello everyone,
This thread is meant to be kind of like a petition, were if there is a considerable amount of people that also want this feature, then maybe Corsair can develop it.
Petition: Add an option in iCUE > Advanced Config > Make brightness key control all iCUE devices.
Reason: When trying to lower brightness/turn off lights, there is no point in doing so only in the keyboard, as the mice and other accessories are not affected. Going into iCUE settings every time is inefficient and making a profile with everything off is not an option, since I am using Wallpaper Engine integration and that overwrites whatever profile you currently have. Enabling this option would make that clicking the keyboard's brightness key will control the brightness for ALL of your iCUE's detected devices, not just your keyboard.
That's all. Thanks everyone.
Miguel
