I have accidentally swipe-navigated far more times than I have ever purposefully swipe-navigated (zero times), so I am astounded to see someone who hasn't rage-disabled that misfeature upon installation of the OS.
I don't begrudge it being overridden here since this is a demo, but ever since, like, way early Opera era, swiping to navigate is muscle memory for me, and I prefer it both on desktop and mobile/tablet. Much simpler than reaching for the button.
Glad you have the ability to set your own preferences, but I’m pretty sure most people are happy with this. Do you by chance spend a lot of time reading PDFs while angry?
