Add option to have starred (or 'sticky') notes move to the top of their folder

I would like to be able to denote which notes are more urgent than others in their respective folder. Since the term ‘pinned’ is reserved for views, and maybe people will not want the existing ‘star’ feature to change behavior, it would be great to have ‘sticky’ notes that will stick to the top of their folder, and have some sort of an indication, e.g. a pin next the them.
