The shadow of some windows is not modified, what to do?

This extension only applies to windows rendered by the cinnamon window manager (a.k.a. Muffin). It is likely that you are dealing with Gtk CSD windows, whose shadow is defined by the Gtk theme you are using.

Hi! Thank you very much for your extension. It works fine and looks amazing. This kind of functionality I was always missing in Cinnamon. May I ask about add one more feature? It will be great if in the custom shadow setup dialog user configure the shadow for 3 sides (left-right-bottom). The shadow will look like in macOS. I think many users of your plugin will be glad to have the ability to configure such shadows. What do you think?
