The auto-scroll text is a native thing on RenPy.
But you have to activate the quickmenu to access it.
It's turned off by default in preferences.
Someone asked a few days ago if Arc could add a way to switch Awaken and Shatter.
In terms of the game itself, no.
Not sure about a laptop cheat... But then people would start asking for switches on every major choice and that pretty much ends up making the choices feel even more pointless than they already are.
I'unno, up to Arc to give a more in-depth reply.
