When I am typing, at least in mobile, I have to manually keep scrolling my screen to see what I'm writing at the bottom of the doc. This is cumbersome, yes, but mostly it makes it more difficult to stay in writing flow when every couple of words I have to stop typing to scroll the screen down more so i can see what i'm typing. And I can't scroll down further to get the cursor more near the top, because the doc doesn't go that far/doesn't allow it.
