Swipe gestures for opening/closing overview
https://gitlab.gnome.org/Teams/Design/os-mockups/-/raw/e8ab80b4eed1049ad78d74f2eac36bbee8f25a70/overview/shell-state-diagram.png contains the state diagram of the new shell design. It is super nice, that nearly everything is connected via touchpad swipe gestures. Well, except the overview, which is the integral part of GNOME shells workflow! This makes the overview feel disconnected and hard to access for touchpad users.
Therefore, I recommend to add a simple three finger swipe up/down to open/close the overview. This would really complete the idea of swipe navigation.
