You can change how your workspace looks in the Dashboard so that when you caption or review a previously recorded session, you can choose whether to focus on your transcript, your notes, or a combination of everything.
Dashboard
In the top right-hand corner, click on the Workspace icon
You will then see a list of options that you can choose to show or hide.
Uncheck the options you don't want to see, and they will be hidden when you review your transcript.
