-              Start a new session in a tab, or open an existing session from any of your projects. Open a new tab when

-            </p>
-            <p>
-              Keeping a few tabs open makes it easier to organize your active sessions. Rename tabs to something
-              memorable if you plan to keep them around.
-            </p>
-            <p>
-              You'll find all your sessions and projects on the new Home screen. Selecting a session opens it in a tab.

-              The new design does not support Git Worktrees yet, it's coming soon. So if you'd prefer to continue using
-              the previous layout, you can switch between layouts in Settings. Just keep in mind that the new layout
-              will become permanent in a few weeks.
