Notes make it possible for co-writers and editors to communicate with each other without having to directly edit the script. Writers can leave themselves notes. Fact-checkers can provide resource links. Readers can provide feedback on specific phrases and selections.
Creating a note is simple. Just place your cursor in the script where you want the note to embed, open up the notes sidebar, and hit "Add Note"
You can adjust the color of the note. Co-writers will often use different colors to communicate with each other. Or teams will use a color grading system to determine when suggestions turn into edits and when they're completed.
The note will appear in the right sidebar and if you want to change the color, edit the text, or delete it, you can do so by clicking on it.
