I would like the 'favorites' feature from Notability implemented along with the additional screen space that GoodNotes has when going into no-writing mode and taping the screen to make the bar go away.

Basically I want an ACTUALLY full-screen paper notetaking experience with a small, customizable, movable shortcuts bar that can fit up to 5-10 preselected pen/size/colors. Aka, a streamlined (Note Taking Mode).
Thanks!
