I think it would be great to have the UV-Scaling boxes arranged vertically, because one can drag over both boxes vertically in blender. That would speed up uniform scaling.
Another nice way to speed up this would be a checkbox for uniform scaling.
LuxCore also has a checkbox for Normalmaps, so that there is no need to add a Normalmap Node separately. Could it be in the Checkbox sRGB/Linear of the ImageTexture Node?
