• Can I change the color of the shadow?

No. The APIs required to do that are not exposed to cinnamon extensions.

• 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! If there is one thing I really wanted to change for the window shadows, it's the color! Because for a dark theme, dark shadows have no use in case stacked windows don't distinguish each other. Even if it seems silly, "light" shadows would do the job just fine. So I am very disappointed. Any possibility to change this? That would be fantastic! Think's C6ril

Wish it were compatible with older Mint like 19.x (Cinnamon 4.2.x). Modified the metadata to add 4.2 compatibility but currently it throws an error on load I don't know how to find the reason for: invalid property id.

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?
