Up/Down for the Overview animation might be misleading
In GNOME 40 tour "Up/Down for the Overview" animation is displaying slow swipe movement. If I try to use three-finger vertical swipe at speed similar to one in animation, I quickly run out of touchpad vertical space and Overview doesn't stay open. You actually need to do a quick swipe to access Overview with three-finger swipe.
Maybe it would be useful to adjust example animation accordingly, to show quick swipe?
