Android 12L on Samsung Galaxy Tab S7 FE is so awesome... The updates to multitasking make a world of difference especially in normal mode (not Dex Mode).
Swipe from the corner to the middle of the screen introduces pop up mode for your apps and you can have lots of apps open..
2 finger swipe on the side of the app introduces multi window mode.
There is the taskbar at the bottom which makes app switching easier although it will take abit of time to master it.
