+
+- **Batch Operations (Delete/Copy/Move/Download/Extract Zip):**
   - **Delete Files:** Delete multiple files at once.
   - **Copy Files:** Copy selected files to another folder with a unique-naming feature to prevent overwrites.
   - **Move Files:** Move selected files to a different folder, automatically generating a unique filename if needed to avoid data loss.
   - **Download Files as ZIP:** Download selected files as a ZIP archive. Users can specify a custom name for the ZIP file via a modal dialog.
-  - **Drag & Drop:** Easily move files by selecting them from the file list and simply dragging them onto your desired folder in the folder tree or breadcrumb. When you drop the files onto a folder, the system automatically moves them, updating your file organization in one seamless action.
+  - **Extract Zip:** When one or more ZIP files are selected, users can extract the archive(s) directly into the current folder.

+    - **Keyboard Shortcut for Deletion:**
+      - A global keydown listener detects Delete/Backspace key presses (when no input is focused) to trigger the delete operation.
+
+- **File Tagging and Global Tag Management:**
+  - **Context Menu Tagging:**
+    - Single-file tagging: “Tag File” option in the right-click menu opens a modal to add a tag (with name and color) to the file.
+    - Multi-file tagging: When multiple files are selected, a “Tag Selected” option opens a multi‑file tagging modal to apply the same tag to all selected files.
+  - **Tagging Modals & Custom Dropdown:**
+    - Dedicated modals provide an interface for adding and updating tags.
+    - A custom dropdown in each modal displays available global tags with a colored preview and a remove icon.
+  - **Global Tag Store:**
+    - Tags are stored globally (persisted in a JSON file) for reuse across files and sessions.
+    - New tags added to any file are automatically added to the global store.
+    - Users can remove a global tag directly from the dropdown, which removes it from the available tag list for all files.
+  - **Unified Search Filtering:**
+    - The single search box now filters files based on both file names and tag names (case‑insensitive).
+
 - **Folder Management:**
   - Organize files into folders and subfolders with the ability to create, rename, and delete folders.
-  - A dynamic folder tree in the UI allows users to navigate directories easily, and any changes are immediately reflected in real time.
-  - **Per-Folder Metadata Storage:** Each folder has its own metadata JSON file (e.g., `root_metadata.json`, `FolderName_metadata.json`), and operations (copy/move/rename) update these metadata files accordingly.
-  - **Intuitive Breadcrumb Navigation:** Clickable breadcrumbs enable users to quickly jump to any parent folder, streamlining navigation across subfolders. Supports drag & drop to move files.

+    - A global key listener (Delete/Backspace) triggers folder deletion with safeguards to prevent deletion of the root folder.
+
 - **Sorting & Pagination:**
-  - The file list can be sorted by name, modified date, upload date, file size, or uploader.
-  - Pagination controls let users navigate through files with selectable page sizes (10, 20, 50, or 100 items per page) and “Prev”/“Next” navigation buttons.

+
 - **User Authentication & Management:**
   - Secure, session-based authentication protects the file manager.
   - Admin users can add or remove users through the interface.
   - Passwords are hashed using PHP’s `password_hash()` for security.
   - All state-changing endpoints include CSRF token validation.
-  - Change password supported for all users.
+  - Password change functionality is supported for all users.
+  - Basic Auth is available for login.
+  - **Persistent Login (Remember Me) with Encrypted Tokens:**
+    - Users can remain logged in across sessions securely.
+    - Persistent tokens are encrypted using AES‑256‑CBC before being stored in a JSON file.
+    - On auto-login, tokens are decrypted on the server to re-establish user sessions without re-authentication.
+
 - **Responsive, Dynamic & Persistent UI:**
   - The interface is mobile-friendly and adapts to various screen sizes by hiding non-critical columns on small devices.
   - Asynchronous updates (via Fetch API and XMLHttpRequest) keep the UI responsive without full page reloads.
-  - Persistent settings (such as items per page, dark/light mode preference, folder tree state, and the last open folder) ensure a smooth and customized user experience.
+  - Persistent settings (such as items per page, dark/light mode preference, folder tree state, and the last open folder) ensure a smooth, customized user experience.

+  - Light mode maintains a bright interface suitable for well-lit environments.
+
 - **Server & Security Enhancements:**
-  - The Apache configuration (or .htaccess files) is set to disable directory indexing (e.g., using `Options -Indexes` in the uploads directory), preventing unauthorized users from viewing directory contents.
-  - Direct access to sensitive files (e.g., `users.txt`) is restricted through .htaccess rules.
-  - A proxy download mechanism has been implemented (via endpoints like `download.php` and `downloadZip.php`) so that every file download request goes through a PHP script. This script validates the session and CSRF token before streaming the file, ensuring that even if a file URL is guessed, only authenticated users can access it.
-  - Administrators are advised to deploy the app on a secure internal network or use the proxy download mechanism for public deployments to further protect file content.
+  - Apache (or .htaccess) configurations disable directory indexing (e.g., using `Options -Indexes` in the uploads directory), preventing unauthorized file browsing.

       - **Delete All:** Permanently remove every file from the Trash after confirmation.
   - **Auto-Purge Mechanism:**
-    - The system automatically purges (permanently deletes) any files in the Trash older than three days, helping manage storage and prevent the accumulation of outdated files.
-  - **User Interface:**
-    - The trash modal displays details such as file name, uploader/deleter, and the trashed date/time.
-    - Material icons with tooltips visually represent the restore and delete actions.

+- **Drag & Drop Cards with Dedicated Drop Zones:**
+  - **Sidebar Drop Zone:**  
+    - Cards (e.g., upload or folder management) can be dragged into a dedicated sidebar drop zone for quick access to frequently used operations.
+    - The sidebar drop zone expands dynamically to accept drops anywhere within its visual area.
+  - **Top Bar Drop Zone:**  
+    - A top drop zone is available for reordering or managing cards quickly.
+    - Dragging a card to the top drop zone provides immediate visual feedback, ensuring a fluid and customizable workflow.
+  - **Header Drop Zone with State Preservation:**
+    - Cards can be dragged into the header drop zone, where they are represented by a compact material icon.
+    - **State Preservation:** Instead of removing the card from the DOM, the original card is moved into a hidden container. This ensures that dynamic features (such as the folder tree in the Folder Management card or file selection in the Upload card) remain fully initialized and retain their state on page refresh.
+    - **Modal Display:** When the user interacts (via hover or click) with the header icon, the card is temporarily moved into a modal overlay for full interaction. When the modal is closed, the card is returned to the hidden container, keeping its state persistent.
+  - **Seamless Interaction:**  
+    - Both drop zones support smooth drag-and-drop interactions with animations and pointer event adjustments, ensuring reliable card placement regardless of screen position.

+## 🔒 Admin Panel, TOTP & OpenID Connect (OIDC) Integration
+
+- **Flexible Authentication:**
+  - Supports multiple authentication methods including Form-based Login, Basic Auth, OpenID Connect (OIDC), and TOTP-based Two-Factor Authentication.
+  - Ensures continuous secure access by allowing administrators to disable only two of the available login options at any time.
+
+- **Secure OIDC Authentication:**
+  - Seamlessly integrates with OIDC providers (e.g., Keycloak, Okta).
+  - Provides admin-configurable OIDC settings—including Provider URL, Client ID, Client Secret, and Redirect URI.
+  - Stores all sensitive configurations in an encrypted JSON file.
+
+- **TOTP Two-Factor Authentication:**
+  - Enhances security by integrating Time-based One-Time Password (TOTP) functionality.
+  - The new User Panel automatically displays the TOTP setup modal when users enable TOTP, presenting a QR code for easy configuration in authenticator apps.
+  - Administrators can customize a global OTPAuth URL template for consistent TOTP provisioning across accounts.
+
+- **Dynamic Admin Panel:**
+  - Features an intuitive interface with Material Icons for quick recognition and access.
+  - Allows administrators to manage authentication settings, user management, and login methods in real time.
+  - Includes real-time validation that prevents the accidental disabling of all authentication methods simultaneously.
+  - **User Permissions Options:**
+    - *Folder Only* gives user their own root folder.
+    - *Read Only* makes it so the user can only read the files.
+    - *Disable Upload* prevents file uploads.
