We're all different - so one man's meat is another man's poison.
With that in mind I prefer to do it this way:
Create a new tag : "pinned" (or similar)
Create a saved search for tag:pinned
Drag the saved search onto the shortcuts toolbar.
I then just tag notes as pinned, and can see all my pinned notes with a single click via the shortcut.
Unpin the note by removing the tag.
