I am begging Samsung at this point to allow the ability to display more than three notifications, when there is available screen space.
From what I understand, having more than three was removed due to the now bar, but I don't use many apps that use the now bar, nor use it for media control.
I believe that Samsung should allow the ability to display more than three notifications again, which would allow for increased productivity due to being able to see more notifications. I use the notifications to monitor cellular information.
Since it's also possible to use Good Lock (when it's updated of course) to move the system clock over to the right, that would allow space for approximately 6 - 7 notifications without the now bar active.
I believe that the way Samsung should handle this is to revert back to OneUI 6 model where it would display as many notifications as possible on the screen.
