Thanks, I tried it in the demo. It works really well! For indexed dithering it would be nice if there was an option to chose a Bayer matrix, like 2x2, 4x4, 8x8.
In the settings panel there are dither options, Haltone dots, halftone lines, Bayer 4x4 and blue noise. I could add the other Bayer matrixes as options. - watch this space
