Thanks. I came here to ask for the same thing. I would also like to see this. I quite often create a Contents page for a course or whatever the notebook is for, but rather than have a Shortcuts list full up with so many pins that it defeats the point of being called a Shortcuts list, the ability to pin such a note at the top of the list would be so, so good.
Right now, I have a .contents tag that I use, and I'll link all the other pages to this page (obviously!), but I still have to go searching for it when I could just click on the notebook and see it right there at the top of the list. Or, just be able to highlight a note so it stands out from all the others.
