Looking for something similar to the old Mac program Superpaint.
I’m a big fan of Acorn. Unfortunately it isn’t free. But it is cheap.
SuperPaint handled both vectors and bitmaps, I’m not aware of a free program which does both. But…
Inkscape is a vector drawing program. Seashore and The Gimp are bitmap painting tools
