Added the dithering brushes I've been using in Aseprite to the freebies page. I'll add Ko-fi links soon. I would say the UI in CSP and Krita are superior in terms of how brushes are managed but as a pixel art program Aseprite does have some good tools available. https://pixelglade.net/resources/freebies/ditheringbrush.html
Ko-fi link is there too if anyone is interested.
