I spend a vast majority of my time writing notes before I begin writing a novel. I’m a plotter, so being able to have the notes at the center of the screen would be much easier on my eyes and neck. Perhaps at the top with the other viewing options like this - “Develop | Outline | Write | Notes”.
I still LOVE the left-hand navigation to view the Notes, like an index or table of contents.
You can click on “Develop” at the top to just focus on your notes, and work with mutliple notes at one time.
