This update is part of my February 7th, 2026 suite of minor upgrades, and I believe it's a significant enhancement for users who appreciate tabbed layouts. I demonstrate how to customize the layout and add these tabs, ensuring you can follow along easily. I also mention that this upgrade can be performed on a free Notion plan and emphasize the importance of locking your databases after modifications. Finally, I clarify that while adding these tabs simplifies task management, current limitations prevent transferring completed subtasks to historical records.
