+# Cleanup: Remove Tournament Mode
+
+## Status: Completed
+
+## Summary
+Removed the "Tournament Mode" view and "Editor Mode" toggle from the Cube Manager. The user requested a simplified interface that lists packs without grouping them into "Boxes".
+
+## Changes
+1.  **CubeManager.tsx**:
+    *   Removed `tournamentMode` state and setter.
+    *   Removed usage of `TournamentPackView` component.
+    *   Removed the "Tournament Mode / Editor Mode" toggle button.
+    *   Simplified rendering to always show the pack list (grid/list/stack view) directly.
+    *   Removed unsused `TournamentPackView` import and icon imports.
+
+## Impact
+*   The UI is now streamlined for the "Host" to just see generated packs.
+*   The `TournamentPackView` component is no longer used but file remains for now.
