To improve user experience and navigation, enhance page titles and section headers by adding:

• Iconography to page titles to visually identify Workspaces.

• Short descriptions under page titles to provide context for viewing and managing Workspaces.

• A consistent color palette for Notebooks 2.0 UI screens to improve cohesion and usability.
