What is a .wb4 extension file? It is in a folder in my Stardock public docs area in the Windowblinds folder, in a folder named Aerometal. There are a couple different Aero folders but I can't get them to appear in Windowblinds, or show up where I can install them. Just not sure what they are, I thought maybe an Icon package or something but it's not matching up to any of those either.
