+# Update Translations for New Developments
+
+## Status
+- [x] Analysis of new features needing translation
+- [x] Update Italian Translations (it)
+- [x] Update English Translations (en)
+- [x] Verification
+
+## Details
+Verified recent developments:
+1. **Warehouse - Categories**: New management of article categories.
+2. **Communications**: Email configuration and logs.
+3. **Training**: New module for courses and training sessions.
+
+I will scan these modules for `t()` calls and update the `translation.json` files in `public/locales/it` and `public/locales/en`.
+
+## Work Done
+- **Warehouse Categories**: Updated `CategoriesPage.tsx` to use `useTranslation`. Added keys for titles, buttons, fields, and dialogs in both IT and EN locales.
+- **Communications**: Updated `SettingsPage.tsx` and `LogsPage.tsx` to use `useTranslation`. Added complete set of keys for settings, fields, actions, messages and log columns in both IT and EN locales.
+- **Components**: Updated `Sidebar.tsx`, `SearchBar.tsx` to use full translations. Added `apps.core.title` and ensure `categories` is available in menu.
+- **Training**: Training module files were not found in the current workspace, so no translations were applied for this module yet. Suggest to review separately when module is available.
