The second panel on the right on the main Adventure Notes page contains your drafts, which are notes that you have not published yet. These are only visible to you. The GM cannot see your drafts.

Click a title to see a preview of the note, or use the small green "Edit" button to make changes. When you are ready to publish a draft, edit the note and change the "Published?" toggle to "Yes" and save your changes. This will move the note from your drafts panel to the main adventure notes list.
