In SpeedyPainter_BUMP, an additional keyboard shortcut (the '4' key) allows you to toggle painting/visualization mode.

When you save an image created with this version, SpeedyPainter exports 3 files: the normal map, the albedo image, and the combined image (normal+albedo) that looks identical to the image seen inside SpeedyPainter. I hope that this version may also be useful to 3D artists who need to generate simple normal maps to simulate material roughness of objects.

In the last link you can see also how to import the exported normal map inside the popular Unity game development platform. You can see additional video demonstations here and here.
