About Milton

Milton is a paint program built around an infinite canvas that feels raster-based but works with vectors. It includes layers, blur, lines, automatic saving on every change, and unlimited undo and redo that persists after closing.

It exports work to JPEG or PNG at resolutions the machine supports. Supported use is described for Windows 7 and up; Linux use is described as compiling the program, and a macOS version is described as still in development.
