Configuration Options:
- Counter Start - Starting number for the counter (default: 1)
- Counter Padding - Number of digits with zero-padding (default: 3)
- Case Control - Convert filename to uppercase or lowercase
- Preview in Processing Chain - See filename patterns when configuring the rename step
Examples:
{original_name}_{counter}→image_001.jpg,image_002.jpgIMG_{counter}_{date}→IMG_001_2025-08-26.jpg{date}_{time}_{original_name}→2025-08-27_14-30-52_photo.jpgbatch_{counter}with start=10, padding=2 →batch_10.jpg,batch_11.jpg
