Can I use my surface pen to draw in lightburn?

When you say “draw in lightburn” do you mean like a paintbrush where you can freely draw and have LightBurn paint an image? Or do you mean using a pen to work like a pointing device in the same way a mouse is used?

If the former then no, there’s no paint tool or equivalent that would work that way. If the latter then yes, you could use a pen to work as a pointing device.
