 - **Ctrl+0 Zoom Reset:** Added keyboard shortcut to reset zoom and pan to fit window (like Photoshop), with visual feedback.
 - **Active Filter Indicator:** Footer now displays active filename filter in yellow bold text for better visibility.
 - **Directory Path Display:** Title bar now shows the current working directory path, centered between menu and window controls.
-- **WARP.md Documentation:** Created comprehensive development guide for Warp AI assistant with architecture, commands, and development patterns.
-
-### Security
-- **Executable Path Validation:** Added comprehensive validation for Photoshop and Helicon Focus executables:
-  - Validates executable exists and is in safe location (Program Files)
-  - Checks file type (.exe on Windows)
-  - Warns about executables outside known safe paths
-  - Detects directory traversal attempts
-- **Subprocess Security Hardening:**
-  - Replaced unsafe `.split()` with `shlex.split()` for proper argument parsing
-  - Explicitly set `shell=False` to prevent shell injection attacks
-  - Added file descriptor management (`stdin`, `stdout`, `stderr` redirection)
-  - Validates file paths before subprocess execution
-  - Uses `close_fds=True` to prevent information leakage
-- **Input Validation:** Added pre-execution validation for image file paths in both Photoshop and Helicon Focus launchers.
 
 ### Fixed
 - **Property Name Mismatch:** Corrected `get_stack_summary` to `stackSummary` in UIState to match QML property naming conventions.
