Its time to upgrade your PC. Now. We don't care you're running a presentation. yeah We'll let you delay it... for now.
Its time to dim your screen. We don't care if you're reading a recipe while you cook. No we won't put a widget to allow this temporarily. We think its better buried in the settings. And you'll have to set it back later.
Its time for feature X to not work or not exist anywhere. We don't care that it worked in the old version. We don't like it.
