Perhaps have it not scroll down as it generates the text? Invariably I have to scroll back to the top to start reading. You could have a mini-hud (growing line, with a small rectangle at the top showing the first page of text) which would let you see at a glance how much text is being generated, without interrupting reading. Or not; ChatGPT just keeps on vibrating the phone (iOS app) during text gen, with hovering arrow in the middle-bottom as a shortcut to jump to the end.
