Simple Image Renamer 0.1
A safe, visual, and fast batch image renamer for Linux.
Simple Image Renamer is a lightweight C++ application designed to make organizing photos painless. Unlike command-line scripts, it provides a full visual interface with thumbnails, live previews of new filenames, and a robust undo system.

Key Features
- Live Preview: See exactly what your files will look like (in blue text) before you rename them.
- Undo Support: Made a mistake? Hit the Undo button to instantly revert changes.
- Pattern Renaming: Easily serialize files (e.g.,
vacation_001.jpg, vacation_002.jpg) using ### placeholders.
- Search & Replace: Switch modes to fix typos or change specific words across multiple files.
- Selective Renaming: Use checkboxes to rename only specific files in a folder.
- Smart Sorting: Sort by Natural Name (1, 2, 10) or Date Modified (keep your vacation photos in order!).
- Visual Thumbnails: Adjustable thumbnail sizes (Tiny, Normal, Huge).
