Now you mention the the screen is inverted every 6 hours. I think you are doing this based on the position of the sun (light versus dark) rather than a step toward preventing screen burn in. And while a change every 12 hours is certainly better than nothing at all, screen burn in will be noticeable after about a year of leaving the Mac switching on 24/7 this way. But for some people, CRT burn in may not matter, especially because many old Pluses already have a fair amount of burn in. But if there could be a feature added to allow more rapid screen inversion, then it would be a step toward protecting the CRT a bit better. Even so, thank you for the work on this great classic Mac app!
