I tested the light properties.
The link between those that are optional and those that are mandatory is coherent.
This new option can be a great help for those who are not comfortable with editing the [font=courier new]PluginFurnitureCatalog.properties[/font] file.

As far as I'm concerned, I would like to be able to add a unmodifiable property because my lights use the [font=courier new]description[/font] property so that they are recognized by the photo plug-in.
