Can you edit this so that it uses the default Unwrap?
Also if possible, it will keep the settings you use? I see here it sets some specific settings for the Smart UV Project, but I want to do a normal Unwrap with a 0.04 margin.

I managed to do it myself, by changing line 34 and 35 to simply bpy.ops.uv.unwrap()
