why does every single flashlight have multiple settings that you have to scroll through?

once a year I email my favorite flashlight manufacturer to ask if they've finally made a flashlight that just turns on and off when you push the button, and every year they're like, "no, but thanks so much for your feedback!"

be honest, have any of you ever used the flashing feature on your flashlight? did it actually come in handy? handy enough that I have to scroll past it every single time I want to turn my flashlight on or off
