I personally really like StartAllBack. I just want a clean classic Windows experience.
Honestly, I feel like they’ve made side loading easier and easier as times go on. Used to be that you’d just get a pop up that installs weren’t authorized for that app, then you had to dig through the settings to enable it. Nowadays the pop up has a shortcut to the correct settings page and even visually flashes the right toggle for you to make it easier to find.
I’m confused by your definition of fossil fuels.
Except, a pressure gage reads the number it’s pointing at. Not 1 hand means the number it’s pointing at and the other means 5 times the most recent digit passed plus 1 for each tick mark.
I’d wager that most people would never even see a pressure gage with two hands. Dual-indicating double-bourdon tube differential pressure gages are quite rare in the real world. Usually for that kind of application you’d go digital.
