That is not how I see it. You can switch the light from "anywhere" as long as it is at the switchbox. There is a beauty and comfort in knowing that to control the lights in the bedroom, I have to physically be in that bedroom. There is nothing more annoying than not knowing when the light may go on or off because someone else may be operating the switchbox. There is nothing more annoying than having to open another application just to change something in the application I am already in. (Not to mention that I may already have Settings open for a different purpose. Now you are forcing me to lose my position in it to go somewhere else because of a completely unrelated application.)

The Settings application is a good place for global (e.g. UI or OS) settings that have no better place. Application settings have such a better place. Unfortunately, like with many other things, a "last resort dump for something we have no found a better place for" has through some misguided twist turned into a glorified central place where everything should go. Amazing how much you can get away with by calling it "modern".

No, no, a thousand times NO!!!
