Don't engineer the stupid out. People will learn how their oil and their vaporizer work in different environments. You would help them learn faster by making a system that is inherently less susceptible to variation.
we can start to play with heating curves
That's the part of the idea that resonates with me. If I could just make the heater do the thing I imagine is best in the moment, my experience would be much better.
I guess the root of your problem is that you sometimes need a browser search history without the browser snoopers, but your browser safeguards are unreliable and have a tendency to leak into a less private process.
Would it be simpler to just do your searches in a default-private browser like librewolf with history deliberately turned on? Safer failure behaviours, better separation from the main process.
