I would love a section where I can write down notes to reference while I am working on a story.
For example, when I am writing a story from a press release I tend to copy the entire press release and paste it into Arc.
I delete sections of the press release containing the information I have rewritten until I am left with just the story I have written.
Another example is when I am putting together a story and need to drop in quotes. I will past all the quotes at the bottom and then copy and paste them where I want them as I go through the story.
A notes section would allow me the freedom to restructure an article without having to open a new tab or mess up my current draft. I have included a concept image of what this could look like.
