Incidentally, another thing I'd consider an option— although not necessarily my preferred option— is if I could go with the gesture navigation, but change it so the back gesture is something other than a side-pull, or like a side-pull and hold or something. I cannot function without having my side-pull gesture inside of apps, plus in my testing left swipes nowhere near the border get interpreted as back gestures.
Some "posts" refer to a "swipe gesture sensitivity" setting but idk what this is.
