Adjust Opacity in LOW LIST view of AEON NOX: SILVO v 9.1.8



I am using KODI v 20.2 on Windows 10 Pro with Aeon NOX: Silvo v 9.1.8.

In the LOW LIST view, I am unable to change the opacity of the area of the view with the list and the plot.  I have searched through the forum and although there are refrences to opacity, I am unable to find the method to adjust the opacity in the skin.

Can somebody please assist me in this matter by telling me how to adjust the opcity?

Thanks for all your help
