Wow, reading the summary of CUA it seems like a dream (even if a few standards like cut/copy/paste, seem awkward) in today’s UI hellscape. Swipe left for the menu. Then tap Settings, then that spawns a modal. Swipe up and down to scroll it if you realize there’s scrolling with an invisible scroll bar, oh nope, you swiped too vigorously, we interpreted that as a close gesture because we animate in our modals from the bottom so that seemed natural to us.
