 # Changelog
 
+## Changes 4/27/2025 1.2.7
+
+- **Select-All** checkbox now correctly toggles all `.file-checkbox` inputs  
+  - Updated `toggleAllCheckboxes(masterCheckbox)` to call `updateRowHighlight()` on each row so selections get the `.row-selected` highlight
+- **Master checkbox sync** in toolbar  
+  - Enhanced `updateFileActionButtons()` to set the header checkbox to checked, unchecked, or indeterminate based on how many files are selected
+- Fixed Pagination controls & Items-per-page dropdown
+- Fixed `#advancedSearchToggle` in both `renderFileTable()` and `renderGalleryView()`
+- **Shared folder gallery view logic**  
+  - Introduced new `public/js/sharedFolderView.js` containing all DOMContentLoaded wiring, `toggleViewMode()`, gallery rendering, and event listeners  
+  - Embedded a non-executing JSON payload in `shareFolder.php`
+- **`FolderController::shareFolder()` / `shareFolder.php`**  
+  - Removed all inline `onclick="…"` attributes and inline `<script>` blocks  
+  - Added `<script type="application/json" id="shared-data">…</script>` to export `$token` and `$files`  
+  - Added `<script src="/js/sharedFolderView.js" defer></script>` to load the external view logic
+- **Styling updates**  
+  - Added `.toggle-btn` CSS for blue header-style toggle button and applied it in JS  
+  - Added `.pagination a:hover { background-color: #0056b3; }` to match button hover  
+  - Tweaked `body` padding and `header h1` margins to reduce whitespace above header

 - **Controller**: Updated `FolderController::shareFolder()` (folderController) to include the gallery-view toggle script block intact, ensuring the “Switch to Gallery View” button works when sharing folders.  
 - **UI (fileListView.js)**: Refactored `renderGalleryView` to remove all inline `onclick=` handlers; switched to using data-attributes and `addEventListener()` for preview, download, edit and rename buttons, fully CSP-compliant.
 - Moved logout button handler out of inline `<script>` in `index.html` and into the `DOMContentLoaded` init in **main.js** (via `auth.js`), so it now attaches reliably after the CSRF token is loaded and DOM is ready.
+- Added Content-Security-Policy for `<Files "api.php">` block to allow embedding the ReDoc iframe.
+- Extracted inline ReDoc init into `public/js/redoc-init.js` and updated `public/api.php` to use deferred `<script>` tags.
