I use outlines a lot, so it would be great if they were more easily accessed on the top left corner. Something like if we could create the option into a shortcut for either Thumbnail/Favorites/Outlines depending on what we need the most at the moment just like with the pen and eraser tool. Also would be great if the option didn't open a pop up and instead a side panel.

A little nitpicky, but would be super helpful and eliminate my use of the documents app and allow me to entirely make the switch to goodnotes for all studying purposes and not just notetaking.
