Thanks for the tips. Really surprised that EN hasn't addressed this issue - especially since, as you say, it's been requested for many years. Such an easy thing to add.
I have notebooks with a LOT of notes in them - things like email templates and blogs - and I find myself scouring long lists of notes to find some that I always go back to reference. Would love a feature similar to Twitter's pinned Tweet - the ability to pin a few of your notes to the top of each notebook. Maybe max the number at 3 or 5? Just add a right click option to each note = Pin to Top.
