Right now if a notification is text-heavy, I have to repeatedly press the down button to view all of it, as the text scrolls line by line (about 1,5 lines per press). This is tedious and tiring.
I suggest to change that to scroll by page of text, as it is when changing between notifications. This way, with one button press one would consistently move to new content. This would make the notifications experience easier, with fewer button presses.
If for some reason you are opposed to this being the default behaviour, a settings toggle would be great also.
