 ## Key features
 
 - Visualize each bit layer (LSB and other layers) per image channel (R/G/B/Alpha).
-- Browse and download each bit-layer image.
+- Color remapping (random palette remaps with 8 generated variants)
 - Integrates and displays outputs from:
   - [binwalk](https://github.com/ReFirmLabs/binwalk) (embedded archives)
   - [exiftool](https://exiftool.org/) (metadata and geolocation)
