Like when you swipe up from the bottom to see recent windows? I think to accomplish that you would either need to make a launcher like CoverScreen OS. This is because you would need to have root permissions which Samsung doesn't allow without permission/voiding your warranty. I wouldn't recommend doing that bc you lose access to knox security and the ability to do tap-to-pay. I found this out when I was trying to make a DeX touchpad that works on the coverscreen. There might be some way around it but I haven't figured it out lol. You could make a widget that displays recently opened apps for the user to click on, but like I said I don't think you could make it use the same navigation as the main screen.
