Ability to pin notes in the notes list
There should be an ability to pin notes to the top of a notes list (not as shortcuts to the sidebar).
This avoids visual clogging on the sidebar, and lets you can have separate pinned notes in every project tag.
This kind of view would give the user useful structure when they are in the project but is blissfully out of the way when they are not.
If you look at the Carl Pullein screenshot attached, you don't really want to see your house moving project if you're researching a video, for example, but while you are planning the house move and decoration, having those main notes anchored with a bunch of reference below seems amazingly useful and really simple to use.
Also, it's a small thing, but the layout Apple's using is good. You open the project folder and the notes, pinned and not, are visually part of the project thing. If you'd pin notes into shortcuts, they're not really part of the project note list visually.
