Maybe linear is the wrong word to use but hear me out. At this point in SFOS design you can partially open the app launcher by holding the scroll.
This works fine for the first page of the launcher but once its completely open a swipe up get you to the second page instead of moving step by step (or scroll by scroll).
This behavior makes apps on the second page move to the top making them hard to reach.
Would be a nice improvement IMO.
