+# Zentral Dashboard and Menu Cleanup
+
+## Stato Attuale
+Completato.
+
+## Lavoro Svolto
+1.  **Pulizia Menu Zentral**:
+    - Verificato che le voci "Clienti", "Articoli" e "Risorse" nel menu "Zentral" erano ridondanti o non funzionanti.
+    - "Articoli" è gestito dal modulo Warehouse (`/warehouse/articles`).
+    - "Clienti" e "Risorse" erano link non funzionanti (`/clienti`, `/risorse` non definiti nelle rotte).
+    - Rimossi questi elementi dal menu laterale (`Sidebar.tsx`).
+    - Appiattito il menu "Zentral" in un'unica voce di primo livello "Zentral Dashboard" che punta direttamente alla home page.
+
+2.  **Nuova Zentral Dashboard**:
+    - Aggiornato `src/frontend/src/pages/Dashboard.tsx` per diventare la nuova homepage "Zentral Dashboard".
+    - La dashboard ora mostra:
+        - Un messaggio di benvenuto con il conteggio dei moduli attivi.
+        - Una griglia di card per ogni modulo attivo, con icona, nome, descrizione e pulsante per aprire l'applicazione.
+        - Gestione dello stato di caricamento e caso di nessun modulo attivo.
+    - La dashboard utilizza `useModules` per recuperare dinamicamente i moduli attivi.
+    - Integrata con il sistema di Tab (`openTab`) per aprire le applicazioni.
+
+## Prossimi Passi Suggeriti
+- Implementare endpoint di backend per recuperare statistiche globali reali (es. numero ordini aperti, valore magazzino, ecc.) da mostrare nella dashboard principale.
+- Aggiungere widget personalizzabili nella dashboard.
