## Key Features

* **Responsive Grid View**: Thumbnails automatically reflow based on window size.
* **Dual Renaming Modes**:
    * **Sequential Numbering**: Use patterns (e.g., `vacation_###`) with adjustable padding and start indices.
    * **Find & Replace**: Quickly swap specific text strings across multiple filenames.
* **Intelligent Ordering**:
    * Natural Sort (e.g., `2.jpg` comes before `10.jpg`).
    * Chronological sorting (Oldest/Newest).
    * **Manual Mode**: Full drag-and-drop support to define a custom rename sequence.
* **Rich Metadata Display**: Each thumbnail shows the file format, original resolution, file size, and timestamp in `HH:mm dd-MMM-yyyy` format.
* **Interactive Frames**: Thumbnails are housed in high-contrast frames that adapt to your system's light or dark theme.
* **Safety Features**: Instant **Undo** for the last rename operation and a "Reload/Stop" toggle for folder processing.
