 - Interrogazione WMS con click/tap sulla mappa.
 - Import di file KML, KMZ, GeoJSON e JSON.
 - Import GeoJSON compatibile con BOM, geometrie singole, array, FeatureCollection e coordinate Web Mercator EPSG:3857.
- Filtro KML/KMZ `solo particelle` attivo per impostazione predefinita, con separazione dei MultiPolygon ed esclusione di GroundOverlay e perimetri del foglio; il layer foglio resta importabile tramite opzione.
+- Filtro KML/KMZ `solo particelle` attivo per impostazione predefinita, con separazione dei MultiPolygon ed esclusione di GroundOverlay e perimetri del foglio; il layer foglio resta importabile e puo essere mostrato o nascosto separatamente.
+- Migrazione automatica dei vecchi progetti: i GroundOverlay `DOC_...` salvati in precedenza insieme alle particelle vengono riconosciuti, separati e nascosti in tempo reale dal relativo check.
 - Inquadramento e pulizia dei layer importati.
 - Disegno di marker, linee, poligoni e rettangoli.
- Modalita rapide Area, Distanza e Cerchio disponibili direttamente sulla mappa, con superficie, perimetro, raggio, circonferenza e lunghezza dei singoli lati.
+- Area, Distanza e Cerchio disponibili nella barra Leaflet laterale, nascosta all'avvio e controllata dal pulsante nel tab Dati insieme agli altri strumenti.
 - Misure permanenti attivabili anche sui layer importati da KML, KMZ e GeoJSON.
 - Toolbar di disegno completa di icone, modifica, eliminazione singola e pulizia di tutti i disegni/POI.
 - Archivio multiprogetto nella cartella privata dell'app, con nome, selezione da elenco, sovrascrittura ed eliminazione.
- Ogni progetto salva file GIS, POI, disegni, traccia e inquadratura; l'inclusione delle particelle catastali rosse e' opzionale.
+- Tab distinti `Progetti` e `Salvataggio`: il primo gestisce archivio e opzioni live di visualizzazione, il secondo esporta selettivamente l'intera mappa in GeoJSON, KML o KMZ.
+- Ogni progetto salva file GIS, POI, disegni, traccia, inquadratura e tutte le opzioni di visualizzazione: sfondo, layer catastali, trasparenza, misure, foglio importato, barra strumenti e preferenze GPS.
 - GPS nativo MAUI ad alta precisione con permessi Android/iOS.
+- Centratura automatica una tantum all'apertura: prima tramite posizione approssimativa della connessione Internet, poi tramite singola lettura GPS se la rete non restituisce una posizione; nessun punto o cerchio viene mostrato e il tracking continuo non viene avviato.
+- Punto e cerchio di precisione del GPS live possono essere mostrati o nascosti dalle impostazioni senza fermare il rilevamento.
 - Marker posizione, cerchio accuratezza in metri, tracciamento percorso.
 - Controllo se la posizione GPS cade dentro un poligono importato o disegnato.
 - Interrogazione WFS ufficiale Agenzia delle Entrate attorno alla posizione GPS per evidenziare la particella catastale corrente quando il servizio restituisce la geometria.
- Mappa a tutto schermo con tab separati Catasto, Dati, Progetti e Impostazioni, adattabile agli schermi pieghevoli.
+- Mappa a tutto schermo con tab separati Catasto, Dati, Salvataggio e Impostazioni, adattabile agli schermi pieghevoli.
 - Ingrandimento oltre lo zoom satellitare nativo senza tessere "Map data not yet available".
 - Tendine concatenate Regione, Comune, Foglio e Particella.
 - Ricerca di localita e indirizzi eseguita nativamente con fallback Esri e OpenStreetMap, senza richieste CORS dalla WebView.
 - Catalogo dei Comuni incluso nell'APK e cataloghi regionali OnData scaricati in cache solo quando servono.
 - Ricerca catastale eseguita dal codice .NET nativo, senza DuckDB WebAssembly nella WebView Android.
- La registrazione della traccia GPS e' disattivata all'avvio; la toolbar di disegno puo' essere mostrata o nascosta dal tab Progetti.
+- La registrazione della traccia GPS e' disattivata all'avvio; la toolbar di disegno completa puo' essere mostrata o nascosta dal tab Dati.
 - Pannello `Layer` accessibile direttamente dalla mappa, con checkbox sincronizzati per confini, numeri particella, fogli, fabbricati, strade e acque.
 - Le particelle cercate possono essere aggiunte una dopo l'altra, mantenendo contemporaneamente sulla mappa tutti i confini selezionati.
 - Comandi separati per rimuovere le particelle selezionate o pulire importazioni, disegni, POI e traccia GPS.
