The Description field is accessible and editable for users since SH3D-7.1.

For variable lights (automatic or daylight), there was a risk of interfering with the management of the rendering plug-in.
Even if I had no feedback in this direction, I preferred to "secure" this management by updating the library with the new option proposed by SH3D-7.2.

According to my tests, several additional properties can have the same name because their identifier is different when they are created.
