+**v0.2.4**

+Added
+    - Added Initialize Project tool to the VS Code extension and standalone app.
+    - Downloads team template files (AGENTS.md, LOCALIZATION.md, .gitignore) from a shared manifest.
+    - Manifest is a JSON file hosted on Google Drive or any direct URL, listing files with name, URL, and description.
+    - Manifest URL is configurable per-user; defaults to the shared team Google Drive manifest.
+    - Google Drive share links are automatically converted to direct download URLs.
+    - Files panel shows a checklist loaded from the manifest with per-file Open button and Refresh/Configure controls.
+    - Destination folder is selectable via folder picker, defaulting to workspace root in the extension.
+    - Standalone stores the manifest URL in config.json and exposes an inline URL editor via the settings (⚙) button.
