I have noticed, that many gdtf attributes in the fixture builder have a wildcard (n) to make multiple of them, but this is often not useful at all. Attributes like Shutter1, Frost1, Focus1 should not exist because they do not have the same function. Mostly they can be descriped as "Shutter" / "EffectShutter" , "LightFrost" / "HeavyFrost" or "Focus", "AutoFocus" , "FocusDistance". Maybe this can be changed to prevent, that it will end up messy^^
