    • The Before image also works as a drop target to set the input image path.
  • Right-click on the palette in the UI to quickly save the palette image with Save As....
  • Additional palettes can be used by placing .PNG files in a Palettes folder in the app's parent directory.
    • Supports up to 256 colors per palette.

    • Sharpen value range: From -100, to 100.

  • Image processing is ~70% faster (Kmeans/Normal) due to improved pixel-color handling.
  • Setting Image Downscale to 0, or 1, now disables downscaling.
  • Palette images are now saved as 1x1 grids, expanding in width.
  • Palettes contain only unique colors, sorted by brightness.
    • Unfortunately, it's not easy to prevent very similar colors from being included.
  • Maximum number of colors changed from 999 to 256.
  • Supported image file types now include: .jfif, .tiff, .tif, and .ico.
  • All spinboxes can be adjusted with the mouse-wheel.
